Stop using github:nix-systems

Lines 23 to 25 in 25e8fd4

	let url = if known_nix_systems.contains(&s) {
	format!("github:nix-systems/{}", s)
	} else {

Rationale

We keep hitting GitHub rate limits despite passing a token at the nixci CLI level:

https://github.com/juspay/omnix/actions/runs/9910699850/job/27381695570

Solution

We could embed all the system lists of https://github.com/nix-systems locally in nixci, and refer to it using local path, which should not require network access.

For now, this seems to do the trick:
