chore(renovate): group datafusion ecosystem deps into single PR

[timvw]

Summary

• Group datafusion*, deltalake, and object_store crate updates into a single Renovate PR
• These dependencies are tightly coupled: deltalake and object_store must be compiled against the target datafusion release
• Individual PRs for these crates will always fail because they can only be upgraded together

Closes: addresses failing PRs #149, #156, #157
