Labelling pull request with module tags based on changed files in the PR #2826

	# This file defines the workflow for labeling pull requests with module tags based on the changed files in the PR.
	# It uses the `actions/labeler` GitHub Action to achieve the same.
	#
	# The workflow is triggered on the `pull_request_target` event which ensures workflow is only run from the master branch.
	# The job `labeler` runs on `ubuntu-latest` and has permissions to read contents and write pull requests.
