Fix CI

And I want to confirm:

• Should disable pages-build-deployment action; it always fails since there is no longer "docs" directory.
• Why use your mirror esctest instead of the original repo for testing?

Thanks! I want to move to DocC for documentation, and follow what I did in SwiftGodot: which is to push the generated docs to a separate tree (because otherwise it makes it hard to search on the repo)

The esctest is so I can control which version is validated against and in case I make adjustments on the test suite.
