include types export for ts4.7 nodenext resolution

[lizthegrey]

See microsoft/TypeScript#47792 (comment)

otherwise, building with nodenext resolution results in:

Hey there, thanks for this contribution!

I wasn't aware that it was necessary to place a path to the typedefs there, but it makes sense.

[lizthegrey]

@fabiosantoscode looks like I got it wrong.

https://www.typescriptlang.org/docs/handbook/esm-node.html#:~:text=%22.%22%3A%20%7B-,%2F%2F%20Entry-point%20for%20TypeScript,types%2Findex.d.ts%22%2C,-%2F%2F%20Entry-point%20for says that types must come first in the exports.

it also looks like that should have been relative (./tools/ rather than tools/)
