fix(Bundler): Enforce Ruby platform when fetching version data

Fetching version data for individual Ruby gems shouldn't rely on
creation order of the gems on RubyGems.org. Instead, use the standard
`ruby` platform as a sensible default (as it already happens in
Bundler's resolving logic elsewhere in the code).

Partially addresses #8695.
