Upgrade gitlab-styles to 7.1.0
Why is this change being made?
This MR upgrades gitlab-styles to the latest version in order to include new cops which check for classes that aren't FIPS-compliant (gitlab-org/ruby/gems/gitlab-styles!113 (merged)).
RSpec/VerifiedDoubles is also included in this upgrade. Existing violations have been fixed in this MR.
