[ruby/rubygems] Fix quote handling in mise format ruby version parsing

The previous regex didn't properly match quoted strings
it would capture the opening quote as part of the version
if quotes were mismatched.
This change properly parses double-quoted, single-quoted,
and unquoted version strings separately.
