Release Docs mention using the constraints for a new dev env, but that's not mentioned in the dev install docs?

🐛 Bug

Here:
https://napari.org/stable/developers/coredev/release.html#update-constraints-files

But when I follow the link, I don't see anything about that.

I think it's a good idea!
There's been a move towards lock files (uv, pixi), so I think it's worth ensuring we mention how someone could replicate our CI test envs.
