Mk/Uses: default version for nodejs

If a port depends on node, a simple:
USES= nodejs
can be added. It is also possible to define a specific version:
USES= nodejs:14
Use as current version the latest LTS version of node.

 You should get into the habit of checking this file for changes each time
 you update your ports collection, before attempting any port upgrades.

+
+  The port framework was updated to use a default version for nodejs.
+  The default version is pointing to the latest LTS version which is
+  currently version 16.
+  You can overwrite this by defining in /etc/make.conf, e.g. version 17:
+  DEFAULT_VERSIONS=nodejs=17
+
+  Or if you would like to stick always to the current version use:
+  DEFAULT_VERSIONS=nodejs=current
+
+  If you would like to use yarn or npm together with nodejs version 17,
+  just install the package that is pulling the wanted dependency to nodejs:
+
+  # pkg install yarn-node17
+  # pkg install npm-node17
