textproc/expat2: update to 2.4.7

From [1]:

Release 2.4.7 Fri March 4 2022
        Bug fixes:
       #572 #577  Relax fix to CVE-2022-25236 (introduced with release 2.4.5)
                    with regard to all valid URI characters (RFC 3986),
                    i.e. the following set (excluding whitespace):
                    ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz
                    0123456789 % -._~ :/?#[]@ !$&'()*+,;=

        Other changes:
  #555 #570 #581  CMake|Windows: Store Expat version in the DLL
            #577  Document consequences of namespace separator choices not just
                    in doc/reference.html but also in header <expat.h>
            #577  Document Expat's lack of validation of namespace URIs against
                    RFC 3986, and that the XML 1.0r4 specification doesn't
                    require Expat to validate namespace URIs, and that Expat
                    may do more in that regard in future releases.
                    If you find need for strict RFC 3986 URI validation on
                    application level today, https://uriparser.github.io/ may
                    be of interest.
            #579  Fix documentation of XML_EndDoctypeDeclHandler in <expat.h>
            #575  Document that a call to XML_FreeContentModel can be done at
                    a later time from outside the element declaration handler
            #574  Make hardcoded namespace URIs easier to find in code
            #573  Update documentation on use of XML_POOR_ENTOPY on Solaris
       #569 #571  tests: Resolve use of macros NAN and INFINITY for GNU G++
                    4.8.2 on Solaris.
       #578 #580  Version info bumped from 9:6:8 to 9:7:8;
                    see https://verbump.de/ for what these numbers do

        Special thanks to:
            Jeffrey Walton
            Johnny Jazeix
            Thijs Schreijer

Release 2.4.6 Sun February 20 2022
        Bug fixes:
            #566  Fix a regression introduced by the fix for CVE-2022-25313
                    in release 2.4.5 that affects applications that (1)
                    call function XML_SetElementDeclHandler and (2) are
                    parsing XML that contains nested element declarations
                    (e.g. "<!ELEMENT junk ((bar|foo|xyz+), zebra*)>").

        Other changes:
       #567 #568  Version info bumped from 9:5:8 to 9:6:8;
                    see https://verbump.de/ for what these numbers do

Release 2.4.5 Fri February 18 2022
        Security fixes:
            #562  CVE-2022-25235 -- Passing malformed 2- and 3-byte UTF-8
                    sequences (e.g. from start tag names) to the XML
                    processing application on top of Expat can cause
                    arbitrary damage (e.g. code execution) depending
                    on how invalid UTF-8 is handled inside the XML
                    processor; validation was not their job but Expat's.
                    Exploits with code execution are known to exist.
            #561  CVE-2022-25236 -- Passing (one or more) namespace separator
                    characters in "xmlns[:prefix]" attribute values
                    made Expat send malformed tag names to the XML
                    processor on top of Expat which can cause
                    arbitrary damage (e.g. code execution) depending
                    on such unexpectable cases are handled inside the XML
                    processor; validation was not their job but Expat's.
                    Exploits with code execution are known to exist.
            #558  CVE-2022-25313 -- Fix stack exhaustion in doctype parsing
                    that could be triggered by e.g. a 2 megabytes
                    file with a large number of opening braces.
                    Expected impact is denial of service or potentially
                    arbitrary code execution.
            #560  CVE-2022-25314 -- Fix integer overflow in function copyString;
                    only affects the encoding name parameter at parser creation
                    time which is often hardcoded (rather than user input),
                    takes a value in the gigabytes to trigger, and a 64-bit
                    machine.  Expected impact is denial of service.
            #559  CVE-2022-25315 -- Fix integer overflow in function storeRawNames;
                    needs input in the gigabytes and a 64-bit machine.
                    Expected impact is denial of service or potentially
                    arbitrary code execution.

        Other changes:
       #557 #564  Version info bumped from 9:4:8 to 9:5:8;
