### What happened?

https://github.com/conda-forge/spyder-feedstock/blob/1c33270a40c7910c8207262274653a3491e93c83/recipe/spyder-menu.json#L160-L175

The above linked json file does not match the menuinst schema but it is not properly linted. According to [the schema](https://github.com/conda/menuinst/blob/cep-devel/menuinst/data/menuinst.schema.json#L667-L672) the highlighted section should contain a `name`, `description` and `command` which it doesnt. Only the `win` section contains it.

(Also the `spyder` json file refers to a non-existing schema)
