Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/35098

Changelog:
[General][Fixed] [react-native-codegen] react-native-codegen : Add Map / indexed object support for TypeScript parser

In flow we can expose Maps via the following syntax in TM specs

`
+getMap: (arg: {[key: string]: ?number}) => {[key: string]: ?number};
`

In TypeScript writing the same spec:

`
readonly getMap: (arg: { [key: string]: number | null; }) => { [key: string]: number | null; };
`

leads to an exception the TypeScript code-gen parser

```UnsupportedObjectPropertyTypeAnnotationParserError: Module NativeTurboModuleCxx: 'ObjectTypeAnnotation' cannot contain 'TSIndexSignature'.
    at react-native-github/packages/react-native-codegen/src/parsers/typescript/modules/index.js:309:23```
```
This change fixes the TypeScript parser
