Further align with `@typescript-eslint/types`

This is an awesome start bc39dcb but sadly there a a few more places that don't match.

A good start would be by having a look at the latest esrap version (or more specifically this pr), and go through the few ignored type-check warnings.

Here is a list of what's currently not entirely correct according to the sepc:

Type	property is	property should be
TSTypeParameter (property name)	typeof string	typeof Identifier
TSFunctionType	parameters	params
TSFunctionType	typeAnnotation.typeAnnotation	typeParameters
TSMethodSignature	parameters	params
TSMethodSignature	typeAnnotation	typeParameters

This is an incomplete list of course. There are also two or there more type errors inside esrap that might be related to this, or to wrong type expectations in esrap. I have excluded those cases in the list above.

Note to self: If we do this we cannot remove the old properties, that would be a breaking change by now, so we gotta keep the old ones around until the next major
