Add references on syncing dependencies with Hatch

Hatch does not have a direct command for syncing dependencies, and
`hatch env create` won't always sync dependencies if they're being
installed into the same virtual environment directory (as they would be
in a Docker image). `hatch env prune && hatch env create <env_name>` is
the current workaround, but it looks like there's some progress being
made on this. This commit will add some links to help follow progress.
