Improve testing framework and auto-merge dependency bumps

[GeckoEidechse]

With how many dependencies FlightCore has, we tend to get a nearly a PR a day to bump versions from @dependabot.

Given that most a patch releases which most likely don't cause issues and it would be kinda insane to test every single one of those manually, I think it would make more sense to just improve our testing capabilities and then at least merge the patch release when CI passes.

Maybe with a delay of a few days so that in case there's some error, the dependency author most likely pushed another release that addresses it ^^
