Feature Request

I think the cache key for the generated project should be improved. There are cases where I'd expect the generated project to be regenerated instead of being taken from the cache. For instance:
https://github.com/rszamszur/fastapi-mvc/actions/runs/2471988430

Cookiecutter dependency was updated but the generated project was taken from a cache. Since the cookie-cutter is responsible for generating, it shouldn't be taken from a cache.

There could be more edge cases like this with the current cache key.
