chore: fix renovate config

* Cargo dependency updates were merged with the lockfile ones, as showcased in renovatebot/renovate#22524 (reply in thread)
* Vulnerability dependencies were not working because of incorrect group configuration
* Merge all lockfile maintenance updates in a sigle PR
* Don't distinguish between major and minor versions in CI dependency
updates. They're now in a single PR.
