- Typescript runtime: adding .js to imports in d.ts files

[mezozawahra]

Description:
1- added the extension .js to all import paths inside declaration files.
2- added index.js to directory imports, i.e import "./atn" became import "./atn/index.js"

This should be a harmless method since both commonjs and esm support it.

@ericvergnaud Hi Sir, Sorry for the inconvenience.
This typing fix should support both CommonJs and ES modules, so should I rename index.d.cts to index.d.ts (even though it works fine for now without naming)?
again sorry for disturbing you, and thank you for you great work.
