Ruby version from file in Gemfile

rubygems got couple of PRs merged which will now enable us to read gem version from files with builtin functions itself. It supports the likes of

• .ruby-version
• .tool-versions (ASDF)

Each are expected to have it’s own format that is currently being used.

These are available from bundler version 2.4.19

Samples below:

# .ruby-version
3.2.1

# .tool-versions
ruby 3.2.1
