Broken jinja formatting in manifest schema (affects "Manifest Reference" docs page)

[GenevieveBuckley]

It looks like there is broken formatting in the "Fields" table from the napari.yaml manifest reference documentation page. See https://napari.org/stable/plugins/manifest.html#fields

You can see that the table formatting breaks at the 'icons' row, probably because the jinja template tries to use dot points in the description. Then the following five fields are not given their own row in the table, which makes it easy to overlook them (it appears like a confusing description for the icon field):

• categories
• schema_version
• on_activate
• on_deactivate
• contributions

This is the file that needs to be edited: https://github.com/napari/npe2/blob/main/src/npe2/manifest/schema.py

Here is a screenshot showing the formatting failure:
