Versions >= 3.0.2 fail with "Resource not accessible by integration" on merge_group event

[croesnick]

Situation

The following workflow fails when triggered as part of a merge queue check:

name: Sample

on:
  merge_group:
    types:
      - checks_requested

permissions:
  actions: read
  contents: read

jobs:
  sample:
    runs-on: ubuntu-latest

    steps:
      - uses: nrwl/nx-set-shas

Observation

As reported in #114 (comment), it works with version 3.0.2. Tested it with 3.3.2 and 4.0.1.

Expectation

Works with all recent versions on merge_group events as well. :)

@croesnick Heyo, I found out through manual testing through pretty much the whole list of scopes, that the following entry was missing for this action to be able to work in a merge group status check. (tested only with 3.3.2, since we havent migrated to node18 yet)
