Missing source distribution for 2.12.1

[mologie]

Hi, it seems issue #1996 has resurfaced. There is no source code available on pypi, so right now installation for e.g. Alpine aarch64 is broken. Commands to reproduce on any platform:

$ mkdir /tmp/testproj
$ cd /tmp/testproj
$ uv init
$ uv add --no-binary confluent-kafka==2.12.1
Using CPython 3.10.18
Creating virtual environment at: .venv
  × No solution found when resolving dependencies:
  ╰─▶ Because confluent-kafka==2.12.1 has no source distribution and your project depends on confluent-kafka==2.12.1, we can conclude that your project's requirements are unsatisfiable.

      hint: A source distribution is required for `confluent-kafka` because using pre-built wheels is disabled for all packages (i.e., with `--no-binary`)
  help: If you want to add the package regardless of the failed resolution, provide the `--frozen` flag to skip locking and syncing.
