Is it possible to run the `{{cookiecutter.project_slug}}/.github/workflows` in CI?

Is Your Feature Request Related to a Problem? Please Describe

I was helping @ruaridhg with a repo that was built using an old version of the cookiecutter https://github.com/UCL-MIRSG/azure-mail/pull/32. The bug was fixed by @matt-graham in https://github.com/UCL-ARC/python-tooling/pull/517.

Describe the Solution You'd Like

What would be really good if there was a way we could run the workflows within the template. I'm not sure how we would do this in an automated fashion. Currently, the template docs are never built, which is how this bug wasn't fixed for a while.

Additional Context

No response

Start by reviewing the template workflows under {{cookiecutter.project_slug}}/.github/workflows and the related fix in pull request 517. Define how those workflows should be exercised automatically, including the template documentation build, and consider the issue complete when CI reliably catches regressions in the generated project.
