chore: re-order and update dependabot config

* chore: re-order dependabot ecosystems

to better match folder structure
1. "general"; `/` (`.github`, `.pre-commit-config`, `docker`)
2. `api/`
3. `docs/`
4. `web/`

* chore: place schedule and cooldown last for all ecosystems

* chore: add dependabot grouping for actions and pre-commit

* chore: remove web group with a single dependency

* chore: don't group api and docs into the same PR group

currently a single PR updates both directories, which is not ideal as they are not related.
