Fixes https://github.com/go-gitea/gitea/issues/39310
The docker install pages tell readers to use `:nightly` / `:nightless-rootless` for the latest development version, but those tags are no longer published — the registry only carries `main-nightly` and `main-nightly-rootless` (plus the per-release-branch `1.x-nightly` tags):
```
$ curl -s https://docker.gitea.com/v2/gitea/tags/list?n=1000 | tr ',' '\n' | grep -E '"(main-)?nightly(-rootless)?"'
"main-nightly"
"main-nightly-rootless"
```
Anyone who followed the rootless page has been pinned to an image that has not been rebuilt since 2025-08-23.
Changes:
- point the docker and rootless docker install pages at `:main-nightly` / `:main-nightly-rootless`, in English and in the zh-cn/zh-tw translations
- use `1.27-nightly` instead of the long gone `1.16-nightly` as the release branch example (the oldest one still published is `1.19-nightly`)
- fix the zh-cn/zh-tw claim that `:latest` installs a development version, and mention the nightly tags there the way the English page does
- render `@dockerVersion@` as `main-nightly` for the next version, so the compose snippets on the unreleased docs no longer reference `gitea:nightly`
Not touched: the 1.22–1.26 versioned docs carry the same stale tag, but those versions are already out of maintenance — happy to include them if preferred.

## Summary
Adds Sealos to the cloud-provider installation page for the current and next
Gitea documentation.
## Why
Sealos provides a public, community-maintained one-click Gitea template. The
entry fits alongside the existing Cloudron, Linode, alwaysdata, and Exoscale
options.
## Proposed files
- `docs/installation/on-cloud-provider.md`
- `versioned_docs/version-1.27/installation/on-cloud-provider.md`
## Validation
- Sealos App Store: https://sealos.io/products/app-store/gitea
- Template source: https://github.com/labring-actions/templates/tree/kb-0.9/template/gitea
- Gitea image: `docker.gitea.com/gitea:1.27.0-rootless`
- Live deployment validated on 2026-07-24
- Verified administrator initialization, login, repository creation, commits,
issues, release uploads, persistence, and S3 upload, read, and delete flows
## Maintenance
I maintain the Sealos template and can update the documentation when its
deployment path changes. Deployment-specific support is handled in the
[Sealos templates repository](https://github.com/labring-actions/templates/issues).
## AI assistance
This proposal was prepared with OpenAI Codex assistance. I reviewed the
deployment evidence and proposed content and will personally handle review
feedback.
