dev-ruby/rubygems: add 3.2.31 with new gentoo profile

This version also updates the gentoo-defaults.rb profile to address
issues with installing gems directly with rubygems or bundler, either as
root or as a normal user.

Bug: https://bugs.gentoo.org/789957
Package-Manager: Portage-3.0.28, Repoman-3.0.3

+# Gentoo policy is to install all manually installed code into

+# ensures that all manually installed gems using "gem install" as root
+# are installed in /usr/local. Gentoo gems are installed in /usr.
+
+# TODO: We used to manipulate the default_dir, but this no longer
+# works since this is now the base for the new "default" gems that
+# ruby 2.6 uses with irb. So default_dir should refer to the system
+# default now. rubygems also provides various hooks so we may be able
+# to use those to install gems in /usr/local by default in a less
+# intrusive way.
