Update Github Actions pipelines' triggers (#24547)
### Description
1. Update Github Actions pipelines' triggers. Make all of them to be the
same.
2. Format yaml files.
Before this change, the pipelines' triggers were set as following:
```
on:
push:
branches: [ main, 'rel-*']
pull_request:
branches: [ main, 'rel-*']
concurrency:
group: ${{ github.workflow }}-${{ github.ref }}
cancel-in-progress: true
```
I set "cancel-in-progress: true" because for pipeline runs triggered by
pull requests if the pull request was updated(a new commit was added
there), the old pipeline runs can be cancelled. However, this setting
doesn't work well for the runs triggered by "push" events for the main
branch. Let's say, we merged a PR , then it triggered this pipeline.
Then before the pipeline is finished, we merged another PR. Then the old
pipeline run will be cancelled. But we do want it to be cancelled. Each
commit in the main branch should be verified.
