(MODULES-11378) Update GitHub Action Ubuntu runner

GitHub is deprecating Ubuntu 18.04 runners on April 1, 2023. This
commit switches all Ubuntu 18.04 runners used in GitHub Actions to
Ubuntu 20.04.

https://github.blog/changelog/2022-08-09-github-actions-the-ubuntu-18-04-actions-runner-image-is-being-deprecated-and-will-be-removed-by-12-1-22/

This commit also updates all instances of the actions/checkout@v2
to actions/checkout@v3 in perparation for the former's deprecation
as part of the NodeJS deprecation.

Additionally, this commit removes a Gem that was mistakenly committed
in https://github.com/puppetlabs/puppetlabs-augeas_core/commit/76e710a94692ecc0c1881c7d7814e84e63ff69db
