github-actionify: cache only .m2/repository

ctrueden · ctrueden · commit 9e104376c0ed · 2021-07-01T14:37:38.000-05:00
Not the entire .m2 structure. Because .m2/settings.xml is generated by
the build script only when it's not already present, and if we cache it,
then CI builds may get stuck with old versions of settings.xml that
aren't regenerated when they should be.
