Check lint and test stdout step should report all missing dependencies in one pass

[merkata]

Currently, the Check lint and test stdout step checks for missing linting dependencies in the tox.ini file and exits as soon as one is not available. If more dependencies are missing, you would get a new error on every consecutive run. It is better to gather all missing dependencies and present this as an output and then fail, permitting the user to fix all missing deps at one pass.

This would be great! Another change that could be good to include is to actually base the required linters on content on the https://github.com/canonical/is-charms-contributing-guide repo

As a workaround, this file can be check for which linters are required: https://github.com/canonical/operator-workflows/blob/main/tests/workflows/test/simple/tox.ini

The benefits of having tests 😉

Exactly, it naturally gets you into a more structured way of reasoning and improving, I like it :)
