NEW .org/plugin-review action

[carstingaxion]

With the set goal in mind to become a versatile community plugin, label-printing

[...] should at every time align with the .org/plugin review standards, at least with the automated part of the review process.

This is where the Plugin Check (PCP) WordPress plugin comes into play, because thankfully there is also a corresponding github action.

Description of the Change

[...] we should introduce this action into our default push and pull_request workflows. This would also be a nice aspect to promote further, saying "We align with the guidelines not only once (like normal), but with every release".

Closes #46

How to test the Change

I hope to see the test running within this PR, to get a basic testing.
