Pin Dask dependency to avoid dask-expr

[wilsonbb]

As noted in #382, we currently do not support dask-expr as a backend, however it became the default Dask backend with the release of Dask 2024.3.0 (See dask/community#366)

Here we pin Dask to be in a range below this version until dask-expr support is fully added.

Build/CI Change Checklist

• If required or optional dependencies have changed (including version numbers), I have updated the README to reflect this
• If this is a new CI setup, I have added the associated badge to the README

Looks good! Docs build issue looks tied to us falling out of date with LSDB

Thanks! I ended up putting a fix for both in #387
