Description

This PR upgrades the Jest version to 27 which comes with support for test retries out of the box.
These should hopefully be more stable then the improvised solution we've been using before, see #389.

This pr also contains a small script to run npm audit fix on all sub folders containing a package-lock.json.
This should also close the open dependabot PRs.
