fix: matchers type is making the global expect unsafe

[kryops]

What:

Port of DefinitelyTyped/DefinitelyTyped#66247, after the types moved here in #511

Why:

See DefinitelyTyped/DefinitelyTyped#64858

How:

Moved the Record<string, any> constraint to the matchers export only, and removed it from the interface that augments the global Jest matchers.

Checklist:

• Documentation N/A
• Tests
• Updated Type Definitions
• Ready to be merged
  

I added a file with the TypeScript test cases from DefinitelyTyped, as they safeguard that the types should work correctly and prevent this issue from regressing. If they shouldn't be part of this repo, feel free to drop the last commit.

This is great, thank you for porting over the type tests. I'm going to test out these changes in my test repos tomorrow and then merge

Thanks @kryops. I pushed a couple of commits to make this compatible with all 3 test platforms that we support and split/duplicated the type tests as such. It actually helped catch an issue with the @jest/globals interface definition.

Also enabled running the type tests in CI.
