chore: give the package page a body and repo links

1.1.2 went out with an empty description on the registry page: without a
readme field there is no long_description, and twine only warns about
that -- it does not block the upload. Add readme and project.urls, and
record the wider lesson in the release procedure: a release is done when
the pages a downstream user actually opens look right, not when the local
steps go green. Also adds the missing step for creating a Release, which
is why the Releases page sat empty through eight tags.

 Gitea 包 registry 是 **owner 级**(`/iomgaa/-/packages/`)不是仓库级;PyPI 元数据不含仓库字段,故不会自动挂到 `PolyGateway/packages`,需在包页面手动 Link to a repository。
