Add script for testing rubygem published package in alpine and debian.

[leoromanovsky]

We had a bug report from a customer about a failure to install inside an alpine and debian environments. The Ruby gems need to be prebuild in the multiplatform repository so this was not expected.

A script is needed to verify that we have coverage in these environments and bug reports can be reproduced.

👉 If there is a failure in this script that means the gem has not been pre-built in the environment.

For reviewers

What other platforms should we add here to get desired coverage? These are the versions we cross compile for? https://github.com/Eppo-exp/eppo-multiplatform/blob/main/.github/workflows/publish.yml#L77-L81

Give me a shout and I'll add them to this PR.

[felipecsl]

thanks!

[felipecsl]

Should we add a github workflow action to trigger this?

Some others popular distributions are busybox, ubuntu, fedora if you're looking to test more, but I think alpine and debian are a good start for now.
