Github_pullrequest example uses non-existing variable `GITHUB_AUTHOR`

[kastl-ars]

Dear maintainers,

the example for the Github pullrequest action uses a variable GITHUB_AUTHOR that does not exist, according to Github's documentation.

      repository: "website"
      token: '{{ requiredEnv "GITHUB_TOKEN" }}'
      username: '{{ requiredEnv "GITHUB_AUTHOR" }}'
      branch: "main"

website/assets/code_example/docs/plugins/actions/github_pullrequest/updatecli.yaml

Line 12 in 5eea1a9

username: '{{ requiredEnv "GITHUB_AUTHOR" }}'

I am not sure if this username setting is required at all, it seems to only be needed for private repositories according to the updatecli docs. So maybe it would be better to remove the complete line to make the example easier to understand for new users.

Kind Regards,
Johannes
