This thing only needs to exist so Serde can decode the response JSON
properly. I'll either get a success, a missing token, *no body at all
which doesnt' make sense*, or some other ApiError text. In all cases,
the crate::Result is returned. This thing doesn't need to be public.
Now that all API functions are the new versions using my gt_tools::Error
type natively, I don't need to map from the reqwest::Error into the
wrapped variant.
For whatever reason, releases and release attachments are separate modules in the Gitea codebase. I'm going to continue mirroring that structure for now.
I think this is the interface I want for uploading release files. There is an extra option to create the release ahead of the upload just in case it doesn't exist. One *should* create it with the create command or through the Gitea GUI so that everything can be properly written into the release info.
Owner and repo are combined into one string the same way Go dependencies or GitHub Actions are named. `<owner>/<repo>`
Each will be fetched from a matching environment variable if not specified on the command line.
Obviously the Gitea API can return errors, which are also JSON strings.
Theres a new error response struct to collect these, and an enum for
Serde to unpack which ever variant happens to come back.
The API token is read from the environment variable `RELEASE_KEY_GITEA`.
"GITEA" is on the end because Gitea itself will refuse to allow users to
configure Act variables starting with the name "GITEA_".
All information about the release is hard-coded right now. I just needed
to see it hit the API and appear on the Gitea page. Hooking up the extra
options is up next.
