Upgrade dependencies and go version

[fmartingr]

This PR updates all dependencies to their latest versions and the go version to 1.19.

I think everything is on place except for one thing: The ginkgo reporter, which had been removed in v2 and I'm not sure how to port that properly since I have no experience with ginkgo and I can't run the e2e suite since my machine is arm64. Would love some guidance or contribution on that. [changes]

Requires an update on the build images: https://github.com/bitpoke/build/pull/11
