CI build for pomelo

[spookyvision]

came up with this GHA config, verified it works locally with act (when run from the pomelo subdir, with the configuration placed in platforms/pomelo/.github/workflows/). When using the actions-rs/toolchain@v1 action for real, we should remove the toolchain variable - according to the documentation it then picks up what's specified in rust-toolchain.toml. override can then probably also be omitted.

James, re installing trunk:

We can also use cargo-binstall which also has an action we use for nextest and stuff: https:/cargo-bins/cargo-binstall#faq
e.g. https:/tosc-rs/mnemos/blob/main/.github/workflows/ci.yml#L86-L87

@spookyvision do you wanna open a PR to add this?

I think it makes most sense to postpone this until netlify is migrated - otherwise I would have done so already (or am I mistaken here?). Can't help much with netlify unfortunately, but I did set up GH pages for my personal profile, so I can provide some experience from that corner.

Ah, got it. Never mind!
