Possible fix for Qt error when opening napari from RELION

[rdrighetto]

Describe your problem
I wasn't able to start napari from the conda environment installed by RELION-5 following the instructions (see error message below). However, a clean installation of a conda environment just for napari with pyqt from conda-forge following the official instructions works fine. I managed to get it working by modifying the relion-5.0 environment specification (see below).

Environment:

• OS: Ubuntu 22.04.3 LTS
• RELION version: RELION-5.0-beta-3-commit-63311fe

Job options:

• Type of job: Exclude tilt-images
• Full command:

`which relion_python_tomo_exclude_tilt_images`  --tilt-series-star-file CtfFind/job015/tilt_series_ctf.star --cache-size 5  --output-directory ExcludeTiltImages/job021/  --pipeline_control ExcludeTiltImages/job021/

Error message:

Please cite the full error message as the example below.

I managed to solve the problem in my system by modifying the environment.yml file as follows:

I can submit a PR but first I'd like to check if this is a reasonable fix. Also not sure about which versions to pin for napari and pyqt in this case.

Thanks!
