chore: update the check template and add labels workflow

[NicholasEllul]

Description

This pull request updates the workflow such that it does not run on forks. This takes a similar approach to what we currently do in other workflows:

metamask-mobile/.github/workflows/update-attributions.yml

Lines 8 to 21 in d9852e0

	is-fork-pull-request:
	name: Determine whether this issue comment was on a pull request from a fork
	if: ${{ github.event.issue.pull_request && startsWith(github.event.comment.body, '@metamaskbot update-attributions') }}
	runs-on: ubuntu-latest
	outputs:
	IS_FORK: ${{ steps.is-fork.outputs.IS_FORK }}
