Carlos Antonio da Silva ad91686b62 Test on Ruby 3+ with Rails 6+ ...

And remove dupe entry in the exclude matrix.

In order to get Ruby 3 working we needed to install `rexml` as part of
the test dependencies, only done on the main Gemfile (Rails 6.1) and the
6.0 versions. (which are the only ones supported by Ruby 3.)

Devise itself doesn't require `rexml` as it does nothing with it, but a
dependency we use during tests seem to require it. I was able to track
it down to omniauth-openid -> rack-openid -> ruby-openid requiring it:

    13a88ad644/lib/openid/yadis/xrds.rb (L1)

So while we have tests using omniauth-openid, we'll need this require in
place as well. Ideally that upstream version of ruby-openid should have
it, but it seems that one isn't updated in a while.
