Fixes CI breaks due to:

* TS 4.8 with https://devblogs.microsoft.com/typescript/announcing-typescript-4-8/#unconstrained-generics-no-longer-assignable-to
* @types/source-map-support with [source-map-support] Improve types DefinitelyTyped/DefinitelyTyped#61841
* MongoDB 6 with https://www.mongodb.com/docs/v6.0/release-notes/6.0-compatibility/#legacy-opcodes-removed

This ensures that asynchronous work done by patching gets awaited
properly. In particular, it prevents unhandled promise rejections.

Fixes #1319.
