Update printer linter to utilize the reusable action

[HellAholic]

This pull request updates the GitHub Actions workflow for the printer linter PR diagnose job. The main change is switching from a third-party diff action to a custom action, with adjustments to how file patterns are specified and how outputs are consumed in subsequent steps.

Workflow action updates:

• Replaced the use of greguintow/get-diff-action with a custom ultimaker/cura-workflows/.github/actions/get-diff action, updating the input parameters to use explicit file globs and including deleted files.

Job step improvements:

• Updated the conditions and input variables for the "Diagnose file(s)" and "Check Deleted Files(s)" steps to use outputs from the new get-diff action, ensuring only relevant files are processed and improving reliability.

Requires: Ultimaker/cura-workflows#54
