Bug fix

Description

Current Github action run

ERROR:  Error installing standard:
	There are no versions of rubocop (~> 1.56.2) compatible with your Ruby & RubyGems. Maybe try installing an older version of the gem you're looking for?
	rubocop requires Ruby version >= 2.7.0. The current ruby version is 2.6.5.114.

Summary of the fix

rubocop requires a newer version of Ruby to successfully bundle. I'm upgrading to the oldest version or Ruby to satisfy the requirement, but upgrading to Ruby 3 also works as well.

Fixes # (issue)
Point to Ruby 2.7

Why should this be added

Is this dead? Can we get this fixed

@jlurena I don't believe this action is used that frequently. If you want something that's similar and gives you more feedback you can use something like this https://github.com/standardrb/standard-ruby-action

This is what standardrb sponsors though... If it's dead they shouldn't sponsor it.
