CFR: Upload application bundle artifacts to GitHub Pages

[amotl]

Problem

Uploading on PRs to GitHub Workflow Artifacts is not enough, because it does not provide good UX for downloading purposes.

About

This patch extends the GHA workflow to additionally upload to GitHub Pages.

GitHub Pages is not a very good upload destination, because artifacts/resources will be added to the repository itself by default, into a branch called gh-pages. Because the total payload size already is 4x ~100 MB, this would blow up the repository size too much, and already gets rejected by default:

remote: error: File tmp/linux-x64/cratedb-cfr is 126.43 MB; this exceeds GitHub's file size limit of 100.00 MB        
remote: error: GH001: Large files detected. You may want to try Git Large File Storage - https://git-lfs.github.com./
