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

Pull Requests パネルの checks にある "Details" ボタンから始め、現在どのように GitHub Actions run URL をブラウザーで開いているかを追跡します。GitHub Actions VS Code extension がサポートする deep-link の動作と、関連する issue #4815 および #5805 を確認します。インストール済みの拡張機能で実行をエディター内に開ける一方、ブラウザーがフォールバックとして残り、設定が尊重されれば完了です。
