Merge #11276: [Docs] Update CONTRIBUTING.md to reduce unnecessary review workload
91c39e38d Update CONTRIBUTRING.md to reduce unnecesarry review workload (Jonas Schnelli)
Pull request description:
The current workload for reviewing pull requests is relatively high and trivial, non-beneficial pull requests tend to slow down the overall development process.
We may want to directly close trivial, non-beneficially pull requests during time of high pull request load.
This PR would prepare for possible direct PR closing.
