[Playwright-GH-Pages] fatal: unable to access 400

Hi, in my workflows I am getting the following error from the "Publish report" step in [ci.yml](https://github.com/nicfv/Pumpchart/actions/runs/21846090579/workflow?pr=13#L232) (link to [error](https://github.com/nicfv/Pumpchart/actions/runs/21846090579/job/63042486852?pr=13#step:3:281))

```sh
/usr/bin/git -c protocol.version=2 fetch --no-tags --prune --no-recurse-submodules --depth=1 origin +refs/heads/gh-pages*:refs/remotes/origin/gh-pages* +refs/tags/gh-pages*:refs/tags/gh-pages*

```

I have a hunch that there is simply a setting I need to change in my repository settings, but the error message here is not helpful at all. Can you please clarify what needs to be done to fix this error, and maybe I could even help by creating a PR with a better error message?

Thanks!
