🚧🚇👌 Improve dependabot config

[s-weigand]

This PR improves the efficiency of dependabot updates by grouping them instead of open PRs for each dependency. It also deactivates autorebase to not unnecessarily spam the CI (we can still use @dependabot rebase or local rebase and push if needed). It also activates dependabot for the staging branch.

Change summary

• 🚧🚇👌 Use dependabot groups to reduce the amount of PRs
• 🚧🚇👌 Disable dependabot auto rebase to reduce CI spam
• 🚧🚇👌 Activate dependabot for staging

Checklist

• [x] ✔️ Passing the tests (mandatory for all PR's)
