Export clj-kondo hook

This exports the clj-kondo hook for `manifold.deferred/both`, along with the other clj-kondo config used internally by manifold.

After upgrading my project's deps from manifold `0.2.4` to `0.4.2`, I started getting unresolved-var warnings from clj-kondo everywhere I use any function that's defined after [this line](https://github.com/clj-commons/manifold/blob/12950654f185c65156a5817f5bec79a3afbfe401/src/manifold/deferred.clj#L466), which uses the `both` macro.

The warnings went away after merging the config from `.clj-kondo/config.edn`, which defines a hook that teaches clj-kondo how to interpret `both`, but which is available only while hacking on manifold itself, into the config in `resources/clj-kondo.exports/manifold/manifold/config.edn`, which is exported to projects that depend on manifold.

There's no change to hacking on manifold itself, because the internal config includes the exported config via `:config-paths`. This seems better than maintaining the clj-kondo config in two places.
