version for the whole matrix, i.e., RubyGems should not be dowgraded
past the default version of the oldest Ruby in the matrix.

+By default, the default RubyGems version that comes with each Ruby is used.
+However, users can optionally customize the RubyGems version that they want by
+setting the `rubygems` input.

+See [action.yml](action.yml) for more details about the `rubygems` input.

+If you're running into `ArgumentError: wrong number of arguments (given 4,

+should be able to fix them by setting `rubygems: 3.0.0` or higher.
