Use prebuilt binaries for fish

[SuperMatt]

The existing fish script was not building correctly so it had never produced a fish binary based on the upstream. As fish provides pre-build binaries, it would be much better to just use those. I have switched from building from source to downloading, using a very similar method to starship (as I've just worked on a PR for that, see #228).

Here's a copy of the build output:

$ sbuild build ./static.official.source.yaml --keep --outdir ./SBUILD-TEST
sbuild v0.1.10
 INFO Building: ./static.official.source.yaml
