[DOC] Installing recOrder into an existing napari environment leads to cryptic errors

[talonchandler]

We've had a few issues where users with existing environments that includes napari try to pip install recOrder-napari then get cryptic errors. For example,

pip install napari[all]
pip install recOrder-napari
recorder reconstruct -h

leads to

RuntimeError: Please remove PyQt5 from your environment with `pip uninstall PyQt5`

and pip uninstall PyQt5 does not fix the issue...instead causing qtpy.QtBindingsNotFoundError: No Qt bindings could be found.

Instead, we can fix the issue with pip install napari[pyqt6]. I am planning to update the RuntimeError message to reflect this.

Whoops. This issue only affects the latest release of recOrder-napari.

If instead you install from the main branch:

pip install napari[all]
pip install git+https://github.com/mehta-lab/recOrder.git
recorder reconstruct -h

then everything works fine.

@ahillsley can you confirm that you ran into this issue from a PyPI installation? If yes, I'll close this issue. (This also means we're overdue for a stable release).
