[DISCUSS] Allow external contributors to run CI without approval

[roryqi]

Recent moves by Apache Infra have changed the policy on GitHub Actions from
"Only requires approval first time" to "Requires approval every time". I
think this is not friendly for getting folks involved in the project and
this increased the cost for committers to process the pull requests. Please
respond to this thread if you are in support of going back to "Only
requires approval the first time" or if you don't believe this is a good
idea please respond as well. Thanks,
Rory
