Lunny Xiao efd26a3d61 Deploy a Cloudflare Pages preview for pull requests (#498) ...

Pull requests now get a Cloudflare Pages preview deployment after the site build succeeds, and the preview URL is written back as the last line of the pull request description.

- `concurrency` cancels the previous preview build when a pull request is pushed again.
- After `make build`, the workflow copies `cloudflare/_headers` into `build/` (same as the production deployment, so the file is never published to S3/CloudFront) and runs `wrangler pages deploy build --project-name docs-gitea-com --branch pr-<number>`, then extracts the `*.pages.dev` URL from the wrangler output.

Notes:
- Pull requests from forks do not receive the secrets, in that case the preview steps are skipped with a log message and the build check still runs.
- Requires `CLOUDFLARE_ACCOUNT_ID` / `CLOUDFLARE_API_TOKEN` (Pages edit permission) and `DEPLOY_TOKEN` (pull request write permission).
