[rubygems/rubygems] Update some specs to pass ruby-head CI

These specs were monkeypatching `RUBY_VERSION`, but that obviously
doesn't change the running ruby to behave any different.

The removal of some features, in particular, `String#untaint`, made
these specs fail, because untaint is no longer available under ruby-core
and bundler calls `untaint` when `RUBY_VERSION` is less than "2.7",
which these specs were overwriting it to be.

Rewrite these specs to not overwrite `RUBY_VERSION`, but still test the
same things.
