Fix exports

[singiamtel]

Please describe your fix:

Properly export TS types as such

Bug:

This breaks testing on bun. Not very relevant but still neat to get it fixed

Testing:

Run `npm run build && bun test``, it should be green now

In general Jarred wants issues like these to be filed against Bun instead of the respective projects.

Also, is this really the only place in the whole tree that needs to be updated? Im suprised nothing else exports types?

I'll try to file a min repro against Bun instead. Some other projects didn't pass the tests in bun, I didn't investigate much
