David Rodríguez f8f3f11ed5 [rubygems/rubygems] Fix only_update_to_newer_versions regression
The `only_update_to_newer_versions` feature flag will enable some new
behaviour in bundler 3 (or maybe earlier if we decide to consider it a
bug fix) that prevents `bundle update` from unexpectedly downgrading
direct dependencies.

This seems reasonable, but the current implementation is adding
additional requirements for all locked dependencies, not only from the
ones in the `Gemfile`. That causes some situations where the `Gemfile`
is edited and will resolve to older versions to start failing.

This commit fixes the problem by making sure extra requirements are
added exclusively for direct dependencies in the `Gemfile`, not for all
direct dependencies in the lock file.
