@SCG82 is this PR still relevant?

Rebased. Yes it's relevant (replaces 'async-exit-hook' module declaration with @types/async-exit-hook, and splits run into a separate file)

👍

Hang on a sec, I'm working on it (moving @types to devDeps)

@christian-bromann ready for review!

Looks good to me

@SCG82 it seems that this PR fails when running a production release (see https://github.com/webdriverio/webdriverio/actions/runs/3793821896/jobs/6451309605). I wonder if we should revert the change or install dev dependencies as part of the pipeline. Many of these files aren't used by users so it wouldn't hurt to keep them out of the deps list. What do you think?
