Require that RubyGems accounts have MFA enabled for the user account

There should be documentation for this, directing to https://guides.rubygems.org/setting-up-multifactor-authentication/. Further, this shall also require that the Gemspec files be updated for each component:

• active_fedora (Update the gemspec to require MFA for RubyGems releases active_fedora#1481)
• bixby (Update the gemspec to require MFA for RubyGems releases bixby#79)
• browse-everything (Update the gemspec to require MFA for RubyGems releases browse-everything#388)

• hydra-file_characterization (Update the gemspec to require MFA for RubyGems releases hydra-file_characterization#64)

As noted by @dlpierce, this would require that an update be made to the Gemspec file, and then a new release published: https://guides.rubygems.org/mfa-requirement-opt-in/
