BUG: GH wont allow us to update GH-Actions

[MathewBiddle]

When the GH-Action tries to pull from the cookiecutter repo, it doesn't like to make changes to existing actions.
https://github.com/hackthackathon/hackathon-template-github/actions/runs/17113891336/job/48540954204

   ! [remote rejected] update-webpage -> update-webpage (refusing to allow a GitHub App to create or update workflow `.github/workflows/gha-pr-add-project.yml` without `workflows` permission)

We have the permissions set appropriately

permissions: write-all

But I think GitHub doesn't want you fiddling with the GH-Actions in a GH-Action.

The changes are minimal:
https://github.com/hackthackathon/hackathon-template-cookiecutter/blob/main/%7B%7Bcookiecutter.hackathon_repo_name%7D%7D/.github/workflows/gha-pr-add-project.yml

https://github.com/hackthackathon/hackathon-template-github/blob/main/.github/workflows/gha-pr-add-project.yml

Not sure what we need to do to fix this one.
