Retrigger CI

- add ansible package type proxying the Galaxy v3 API
- rewrite href/links/download_url back to the remote so tarballs flow through it
- forward the query string for providers that opt in, keeping Galaxy pagination working
- add a UI usage snippet and an ansible e2e caching case

-### Local cargo registry
-
-A local `cargo` repo is a private crate registry: it serves the sparse index and
-the Web API publish, yank and unyank endpoints, so `cargo publish` works against
-it directly.
-
-```toml
-[registries.<repo>]
-index = "sparse+https://artifactapi.k8s.syd1.au.unkin.net/api/v1/local/<repo>/"

-
-cargo requires a token for publish/yank (`CARGO_REGISTRIES_<REPO>_TOKEN`); like
-other local repos, artifactapi does not check it.
