CI: Check/lint dependencies for changed integrations #1411
Description
We recently discovered an issue with changes in dependencies not being properly identified as issues by CI (e.g. in #1404)
As such we should discuss a solution that properly identifies dependencies and adds them to our CI checks when included in a changed mixin.
Current idea would be inserting a pre-matrix job check to the linting to recursively discover dependencies for all changed mixins, deduplicate the resultant array, then add it to the matrix so they can all be tested simultaneously.
