Hello, it seems that one my previous PR (adding the sparse index to the
cargo package content page), did not worked as expected: the
gitea-origin-url does not add the AppURL because of the `sparse+` prefix
in the url.
Currently the rendered page gives the following:
```toml
[registry]
default = "gitea"
[registries.gitea]
index = "sparse+/api/packages/ownername/cargo/" # Sparse index
# index = "https://git.example.com/ownername/_cargo-index.git" # Git
[net]
git-fetch-with-cli = true
```
