### What this PR does / why we need it?
- This PR removes several self-hosted runner labels from the
`actionlint.yaml` configuration file. These runners are likely no longer
in use, so this change cleans up the configuration and ensures
`actionlint` has an accurate list of available runners.
- Move all Action dockerfiles to one folder
- remove useless `runner` input for e2e test.
- update workflow option version
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
This is a configuration change for the CI linter. The correctness will
be verified by `actionlint` running in CI on subsequent pull requests.
