Documentation missing for operators in typescript declaration files

[keegancsmith]

This leads to hovers in vscode only including the type information, rather than the documentation additionally.

RxJS version: 5.5.2

Expected behavior: Documentation for operators in the respective .d.ts files.

Actual behavior: Most operators do not have documentation.

Additional information: I am importing operators like this import { switchMap } from 'rxjs/operators/switchMap'. I've noticed missing documentation on fromEvent, pipe, filter, subscribe, distinctUntilChanged, switchMap.

Hi @keegancsmith please close this issue as the operators:

• fromEvent
• filter
• distinctUntilChanged
• switchMap

as well as the pipe and subscribe functions are documented now.
