automated pull request workflow

[Remi-Gau]

The template in the repo for the automated pull requests was giving me lots of failures:

https://github.com/cpp-lln-lab/CPP_ROI/actions/runs/2518984368

Fixed by using another github action to open the PR at the end of the workflow:

https://github.com/cpp-lln-lab/CPP_ROI/blob/96350f5100057c607eaf8dae16363ea229e7f08a/.github/workflows/update-contributors.yml#L40

Side note:

Using this automated PR with certain pre-commit hooks (end of file fixer?), leads to an "interesting" bot version of a tug of war

This version is quite old:

tributors/examples/automated-pull-request.yml

Line 85 in de944de

uses: vsoch/pull-request-action@1.0.6

and we should update to latest (with many bug fixes).
