fix(types): Copy types from DefinitelyTyped

[kachkaev]

This PR partially addresses #191 (see #191 (comment) → step 1). The file was copied from DefinitelyTyped.

Let me check the changes locally before removing the draft status. If anyone spot anything in the meantime, feel free to raise it in the comments 🙂

I tried to keep the file as close to the original to avoid accidental breaking changes.

UPD: I made the same changes locally and the typings were successfully read. Removing the draft status.

It's a pity we are loosing the tests that are present in DefinitlyTyped.
We should add them as before we make any relevant changes.

Besides that: LGTM

cc @tkqubo, @karfau (you are mentioned in DefinitelyTyped → index.d.ts) 👋

UPD Oops I forgot to call a string comparison function in my head before cc-ing @karfau 😂

[kachkaev]

Yeah I completely agree on the tests. This fix we are making is quite rough, but it looks justified given the state of urgency 🙂

Need to get some sleep now, but will release it soon.
