[rubygems/rubygems] Remove `RUBYGEMS_GEMDEPS` warning

When setting the `RUBYGEMS_GEMDEPS` environment variable to allow
skipping `bundle exec`, `bundler` will print a warning about potential
incompatibility.

Initially the `RUBYGEMS_GEMDEPS` variable used a completely different
(re)implementation of `bundler` functionality. That implementation was
not battle tested and could potentially differ in behaviour from what
`bundler` does. That's why print a warning.

However, these days, all `rubygems` does when `RUBYGEMS_GEMDEPS` is set
is to require `bundler/setup`, so there's no risk of any
incompatibility, since that's just plain `bundler`.
