Subject: [PATCH] Add type definitions for promise-map-limit package (#25550)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add type definitions for map-promise-limit library

* map-promise-limit → promise-map-limit

A typo…sigh. The GitHub repository link to promise-map-limit was previously correct, however.

* Remove additional TSLint rule

Thanks @plantain-00!
