update conda_menu_config.json for latest fixes in menuinst

[jaimergp]

Description

Comes from napari/packaging#62, where I had to introduce some changes in the menu config JSON file. I am now backporting this to the source repo so the conda-forge recipe receives these updates too.

Type of change

• Bug-fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

References

How has this been tested?

• The original PR is passing.

Final checklist:

• My PR is the minimum possible work for the desired functionality
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• I have added tests that prove my fix is effective or that my feature works
• If I included new strings, I have used trans. to make them localizable.

thanks for working on this @jaimergp! is the dev branch of menuinst using some sort of pydantic validation we could use to just check the json is valid and remains being valid 🤔 ?

Maybe have a menuinst.api.validate method 🤷🏼

It's under menuinst._schema, but in order to avoid one more dependency in conda (conda depends on menuinst), this not used at runtime. Instead it's technically done during conda-build (see the upstream summary issue for the conda-build PR). To be revisited because conda is changing some strategic points and we might see a pydantic dependency in the future anyway.
