Provide a way to update content_hash in pdm.lock without updating

[blueyed]

In case of merge conflicts you might have to update the content_hash based on the merged result (if not taking one alternative completely).

There appears to be no command to update/verify/rewrite the lock file without updating it, is there?

I've tried pdm lock, which does not have --no-update like e.g. poetry. I think this could be a good option here also?

(I've also tried pdm update --update-reuse, but it would still update versions.)

As far as I can see it gets done currently implicitly with pdm install:

Lock file hash doesn't match pyproject.toml, regenerating...

I think it would be useful if this would also update the hashes, e.g. when you've added/changed sources.
(I can create a new issue / feature request if needed, but thought it is very much related to this issue here already)
