Fine-tune `turbo.json` config to improve cache hits (#10377)

* play with turbo configuration

* tmp: random change, let's test caches

* remove unnecessary inputs

Inputs are implicit via the `"dependsOn": ["//#build"],`

* use `inputs` instead of `outputs` for `//#style`

* Revert "tmp: random change, let's test caches"

This reverts commit 77e9be6dc41bc432bee7589f77d8b9fc02369e2a.
