ci: linting on generated code

[mimatache]

This PR will run golangci-lint against all the generated repositories.

Things to improve:

• Don't install golangci-lint for each item in the matrix
• Uses golangci-lint predefined action
• Add a .golangci.yaml file with desired linter configuration

resolve #39

Checking out this PR and on your local branch I see that all the builds are failing 🤔

Is there working pipelines that I can see 😓

What is failing is not the new workflow, but the one was already failing the main repository earlier that is breaking my actions as well:

I can't seem to get the actions to trigger right now (didn't even see them running on mine before). Do you have any advice on how to get them to run (note, my workflow might not event start until it was merged into main).

@Melkeydev can you try approving the workflows so we can see if they run/pass here? I don't have the option from my branch to run it.
