fix(ast/estree): fix TS type defs for TSIndexSignature and TSIndexSignatureName

[overlookmotel]

Follow-on after #9968. These 2 types are TS-only, so none of the fields are optional. Correct TS type defs by replacing TSNull with Null etc in the extra field types.

cc @therewillbecode @hi-ogawa FYI.

Note: It doesn't matter that this adds the extra fields in JS-only raw deserializer in deserialize-js.js, because those deserializer methods are dead code anyway in JS-only deserializer. I'll remove them entirely from the JS deserializer code at some point.
