Move website deploy from Travis to GH Actions (#887)

* Moves all GH publish steps out of the publish script, and updates the built directory structure to better mirror the final output.
* Since this script is now safe to run locally, rename to `build.sh` and update the npm script to use this directly.
* Add actions-gh-pages to the github actions workflow, renaming to CI.
* Removes references to Travis CI.
