Update MongoDB driver dependency (TS declarations for ~4.1.0 are full of errors)

[JL102]

• Summary
  The TypeScript declarations for the 4.1.x MongoDB driver are full of errors, so it is currently impossible to build a TS project which has connect-mongo as a dependency.
  I made a fork for my own purposes and changed "peerDependencies": { "mongodb": "~4.1.0" } to "peerDependencies": { "mongodb": ">=4.1.0" }, and it appears to work fine. Alternatively, updating to either ~4.5.0 or ~4.6.0 (to avoid potential future breaking changes) would be great.

• Other information (e.g. detailed explanation, stack traces, related issues, suggestions how to fix, links for us to have context, eg. StackOverflow, personal fork, etc.)

P.S. these errors occur even when you add node_modules to the exclude list in tsconfig.json.

Thanks!
