chore(actions): support cron schedule task

[lunny]

Replace #22751

1. only support the default branch in the repository setting.
2. autoload schedule data from the schedule table after starting the service.
3. support specific syntax like @yearly, @monthly, @weekly, @daily, @hourly

How to use

See the GitHub Actions document for getting more detailed information.

on:
  schedule:
    - cron: '30 5 * * 1,3'
    - cron: '30 5 * * 2,4'

jobs:
  test_schedule:
    runs-on: ubuntu-latest
    steps:
      - name: Not on Monday or Wednesday
        if: github.event.schedule != '30 5 * * 1,3'
        run: echo "This step will be skipped on Monday and Wednesday"
      - name: Every time
        run: echo "This step will always run"

I tested here with latest nightly (rootfull) docker build and a dumb workflow.
The feature works well.

Many thanks @appleboy , @lunny and reviewers 👍
