In trying to create a pull request with a push to to gh-pages I get this error in my action:

Push the commit or tag
  /usr/bin/git push origin gh-pages
  remote: Permission to pyuvm/pyuvm.git denied to github-actions[bot].
  fatal: unable to access 'https://github.com/pyuvm/pyuvm.git/': The requested URL returned error: 403
  Error: Action failed with "The process '/usr/bin/git' failed with exit code 128"

I have given workflows permission to write in settings:

I’ve also tried added permissions to my YAML file:

name: documentation

on: [push, pull_request, workflow_dispatch]

permissions:
  contents: write
  pull-requests: write


jobs:
  build:
    runs-on: ubuntu-latest
    permissions:
      contents: write
      pull-requests: write

However, the log file suggests that my permissions are being thwarted:

What am I doing wrong?
