Unblob wheel doesn't contain the rust binding

[vlaci]

The release build differs from how we build it for the docker image:

unblob/.github/workflows/build-publish-image.yml

Line 28 in c5837b7

run: UNBLOB_BUILD_RUST_EXTENSION=1 poetry build --format wheel

unblob/.github/workflows/release.yml

Line 18 in c5837b7

- run: poetry publish --build

I'd adwise to build wheels for all main branch merges and store¹ them as artifacts. Tests should also run against the wheel built that way. The release should just fetch² the artifact matching the tag and publish it. That way we ensure that the wheel is tested and works properly.

Also, the wheel contains the rust source code.
