Expand github actions to build for other ruby versions #4
Description
By default we configure the project with SKETCHUP_VERSION=2024. This in turn sets up the RUBY_VERSION=3.2.
I don't think there is a need to have actions for every sketchup version, but we should definitely do one for each ruby version.
I would suggest the following for the moment:
- One set of actions targeting 2021 (2.7 ruby and the earliest version we support)
- One set of actions targeting 2024 (3.2 ruby and the latest version we support)
