This change brings in version 3.5.6 of OpenSSL, which features
several security fixes (the highest of which is a MEDIUM severity
issue), as well as some miscellaneous feature updates.

Please see the release notes [1] for more details.

PS Apologies for the confusing merge commits -- I was testing out a
new automated update process and failed to catch the commit message
issues until after I pushed the change.

Merge commit 'ab5fc4ac933ff67bc800e774dffce15e2a541e90'

This change adds OpenSSL 3.5.5 from upstream [1].

The 3.5.5 artifact was been verified via PGP key [2] and by SHA256 checksum [3].

This is a security release, but also contains several bugfixes. All of
the CVE-worthy issues have already been addressed on the target
branch(es), so the net-result is that this is a bugfix release.

More information about the release (from a high level) can be found in
the release notes [4].
