Improve online runner check (#35722)

This PR moves "no online runner" warning to the runs list. 

A job's `runs-on` may contain expressions like `runs-on: [self-hosted,
"${{ inputs.chosen-os }}"]` so the value of `runs-on` may be different
in each run. We cannot check it through the workflow file.

This PR also splits `prepareWorkflowDispatchTemplate` function into 2
functions:
- `prepareWorkflowTemplate` get and check all of the workflows
- `prepareWorkflowDispatchTemplate` only prepare workflow dispatch
config for `workflow_dispatch` workflows.
