Open Github Action checks in Github Actions extension

Feature Request

When viewing PR checks in the Pull Requests panel, the "Details" button currently opens the GitHub Actions run URL in the browser. It would be great if there was an option (or setting) to instead open the run in the GitHub Actions VS Code extension, keeping the workflow visible within the editor.

Motivation

Many developers already have the GitHub Actions extension installed alongside this one. Switching to the browser to view a workflow run breaks flow — especially when debugging a failing check and jumping between logs and code. A deep link to the Actions extension would keep everything in one place.

Suggested Behavior

When the GitHub Actions extension is installed, the checks "Details" button opens the run in that extension
When it's not installed, fall back to opening the browser (current behavior)
Optionally, a setting like githubPullRequests.checksOpenIn: "browser" | "actionsExtension" to let users choose

从 Pull Requests 面板中的 checks "Details" 按钮开始，跟踪它当前如何在浏览器中打开 GitHub Actions run URL。查看 GitHub Actions VS Code extension 支持的 deep-link 行为以及相关 issue #4815 和 #5805。完成标准是已安装的扩展可以在编辑器中打开此次运行，同时浏览器仍作为 fallback，并且遵循任何 setting。
