LICENSE is not packed in source distribution

Looking at the source distribution of our latest release, I'm not seeing the LICENSE file:

❯ tree ~/Downloads/icechunk-0.1.0 -L 2

We probably need to change something in pyroject.toml to make this work.

We specify it by name in pyproject. We currently only have the license file in the root directory which cannot be packaged because its in a parent directory. Prob need a symlink
