Create rule schema to support "allowComments"

eslint v9 made schema mandatory for options supported
by rules:
https://eslint.org/docs/latest/extend/custom-rules#options-schemas

Previously we didn't use the meta object on the rules
so now we create the meta object and populate the `schema` property.

Thanks to @BePo65 for providing context, docs and the schema itself.
