Show Deployments in pull request details page

I'd be nice if we could open deployments right from vscode. The design would be very similar to how the PR checks are shown:

Pretty useful if you have preview deployments, E2E test result reports (w/ playwright for example), coverage reports, etc

Instead of "Details" it'd be "Open", and the status, icon and name are pretty much the same thing for deployments:

首先检查 VS Code 扩展中的 PR 详情页面如何呈现 PR 检查，然后确定 pull request 可用的 GitHub deployment 数据。完成的标准是显示 deployment 及其状态、图标和名称，并且 Open 操作可以启动每个 deployment 或 report。
