Auto-merge more dependencies

Created by: felixfbecker

I'd like to increase the number of packages that we automerge so we spend less time with upgrades in our upgrade week.

Currently we automerge @types/ packages, because these are guaranteed to only affect compilation (type errors) and therefor errors are caught in CI.

As a next step we could enable automerging of all devDependencies (webpack etc). These can have effects, but usually it would be that they break the whole site, which we catch with our e2e tests.

For even more automerging, we would need to extend our e2e tests more to cover the tasks we would do as humans too. Currently though whole pages are never navigated to (e.g. the API console, which means we can't automerge graphiql or any related packages).
