fix: include uv.lock in release tarball

[geruh]

Rationale for this change

Include uv.lock in sdist so dependency resolution matches the release branch.

Are these changes tested?

Yes

No

LGTM

this should be included. we added poetry.lock in #2405 for the same reason.

i guess this was missed during the uv migration, #2601 (review)
i dont see uv.lock in the "new" section

I think this is reasonable, but would there be a way to include a ASF 2.0 license? Otherwise we might need to add an exclusion to the license checker.

[kevinjqliu]

we already have uv.lock in the rat exclude
