manual on configuration: https://w3c.github.io/spec-prod/#deploy-to-w3c-using-echidna
configuration example: https://github.com/w3c/pointerevents/blob/gh-pages/.github/workflows/auto-publish.yml
(example is almost just to copy, with editing several parameters)
configuration example for bikeshed: https://github.com/gpuweb/gpuweb/blob/main/.github/workflows/publish-specs.yml

forgot to configure W3C_TR_TOKEN from Settings -> Secrets configuration. Need to check other repositories.
Also need to confirm it's working on webxrlayers spec. (wait for next PR merged)

waiting for speced/bikeshed-boilerplate#11, hope we could run GHActions without error after that PR.

still having random errors which requires bikeshed-boilerplate update, but all completed.
