Fix deps io replace for rubygems and bundler

What does this MR do?

Fix deps io replace for rubygems and bundler

Deps io collects the latest tag for each `replace_in_files` but only the
last result is kept. Because of this all rubygems/bundler versions are
replaced with one version.

This workaround only looks for the minor version of rubygems and
replaces all rubygems/bundler versions with it. The major version has
been moved to the replace pattern.
