The set-output command is deprecated and will be disabled soon

[joey-ma]

I was just browsing around and noticed a new warning within GitHub Actions' workflow Annotations.
Will come around to work on this another day as GitHub's plan to fully disable current commands won't be until May 31st, 2023.
Creating issue now as a reminder though before waiting to see fail messages starting June 1st, 2023.

Overview

For example, both

• Check Ruby Version and Open New Issue on Change #147
• Check Github Pages Gem Version and Open New Issue on Change #146
  now have this same warning:

The `set-output` command is deprecated and will be disabled soon. 
Please upgrade to using Environment Files.
