[algoliasearch] change module format (#37284)

* [algoliasearch] change module format

TBH I'm not really sure what the difference is, but this doesn't break any tests on my repositories. It was needed to work with `/// reference` imports (cc @samuelbodin)

I also had to remove the Omit type for some reason to rely on the builtin one, I guess that's not too big of a deal?

* update algoliasearch-helper too

* more updates 🙈

* modern module format & revert TS version changes

* Update types/react-instantsearch/index.d.ts
