The docs for getting SSH working when using the Docker installation report a different env var name than the one that is actually stored in `app.ini`. - `app.ini`: `SSH_AUTHORIZED_KEYS_BACKUP `: https://github.com/go-gitea/gitea/blob/06eaf74e8a91dcf2254e29e9e5a7829c0e2d4aee/custom/conf/app.example.ini#L318 ([link](https://github.com/go-gitea/gitea/blob/06eaf74e8a91dcf2254e29e9e5a7829c0e2d4aee/custom/conf/app.example.ini#L318)) - Docs: `SSH_BACKUP_AUTHORIZED_KEYS` ([link](https://docs.gitea.io/en-us/install-with-docker/#ssh-container-passthrough)) I assume the docs are out of date and will issue a PR.
