Motivation: I want to replace `cargo-cranky` with workspace lints, first
available in Rust 1.74.
However, `cargo doc` would hange on `wgpu` and `wgpu-core` on 1.74 and
1.75… so now we're on 1.76.
I think this is fine - when 1.78 is released next week we're still two
versions behind the bleeding edge.
…and the branch name is just wrong 🤦
The goal is to host the egui web-demo on its own `gh-pages` branch, and
have the CI build and publish a new demo on each merged CI.
Let's see if I can get this to work…
