Support the various file formats found in .ruby-version files.

3.2.2
ruby-3.2.2

Also supports .tool-versions files for asdf. Lines not starting with “ruby” are ignored.

ruby 2.5.1 # comment is ignored
ruby   2.5.1# close comment and extra spaces doesn't confuse

Intentionally does not support ‘3.2.1@gemset` since rvm recommends using .ruby-gemset instead

    file_content.strip
