Fetch live test262/Wasm results instead of relying on a triggered build

The website currently only updates when the libjs-website repository is
updated. That is, it is not updated when new test results are published
to the libjs-data repository. Instead of setting up inter-repository GH
Actions hooks, just pull fresh data from libjs-data when loading the
website.
