* Merge RubyGems-3.5.4 and Bundler-2.5.4
* Merge RubyGems-3.5.5 and Bundler-2.5.5
* Make tests play with upstream Ruby tests
CI broke in https://github.com/ruby/ruby/pull/9604 because if any Ruby
tests run `require 'net/http'`, they will pollute the
`$LOADED_FEATURES` for the RubyGems tests. We can fix this by renaming
the test default gem from `net-http` to `my-http`.
See https://github.com/rubygems/rubygems/pull/7379#issuecomment-1901241299
for more details.
