* feat: add dependabot auto merge & grouping
Adds grouping for Dependabot PRs, meaning we no longer need to manually group PRs that fail tests due to incompatible groups.
Adds auto-merge of Dependabot PRs when they pass all tests.
* roll back dependabot label changes
* use secrets.GITHUB_TOKEN for automated PRs from Dependabot
* Automerge Dependabot PRS, use REPLICATED_GH_PAT for secret
* amend and simplify auto-dependabot job
* simplify PR jobs
* remove CODEOWNER ownership for go.mod
* Update .github/workflows/automated-prs-manager.yaml
