Does not compile with TypeScript

Do you want to request a feature or report a bug?

Bug

What is the current behavior?

Unable to compile due to message Cannot find type definition file for 'mongoose/types/cursor'.

If the current behavior is a bug, please provide the steps to reproduce.
Try compiling with any typescript project.

What is the expected behavior?
Compiles without errors.

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.

Mongoose: 6.2.5

Seems the types cursor file is of the wrong file extension. Needs to change from .ts to .d.ts

As a follow up to this, it seems Typescript is still passing GitHub checks, those aren't currently working.

I can confirm both, doesn't happen with 6.2.3

I will have a look at it.

Which version of typescript do you use and what is your tsconfig?

[Uzlopak]

I see it. I messed up with the filename. It should have been cursor.d.ts and not cursor.ts.

In regard to avoid again such a regression I added in #11516 logic to validate that we only have .d.ts files in types folder.
