Fix a bug in the types.
What changes did you make? (Give an overview)
This PR fixes the type integration tests in ESLint which would currently fail with
@eslint/[email protected](eslint/eslint#19098).The fix consists in marking the properties of generic interfaces as non-optional, meaning that they can't be
undefined. These properties are only used to refer to a type. For example there is no actual object with a propertyMessageIds, butRuleDefinitionTypeOptions["MessageIds"]is used as an alias forstring. If a union withundefinedis desired, it can always be indicated explicitly asRuleDefinitionTypeOptions["MessageIds"] | undefined.Related Issues
