Should/could we submodule npe2 instead of explicitly cloning it in prep_docs.py

So. Submodule is pinning given reference of submodule repository. So it means additional maintenance steep to synchronize with releases of npe2. Current code first clone, then checkout revision that fits to latest released npe2 version.

If we are just cloning latest a specific tag, can't we continue doing that with a submodule?

Currently, this is what we do: https://github.com/napari/docs/blob/0c7029e5c9674e9d56c5efbec1022fa302661280/docs/_scripts/prep_docs.py#L26C1-L26C74

I'll do some research on whether we would get any clear benefits from using a submodule (discussed in the docs WG meeting)
