Button to go to linked issue to PR

In the browser I can get to the linked issue this PR addresses from the Overview page and it's of course important sometimes to refer to the original requirement during the review.
And issue can be already viewed in the app so it would synergize nicely.

从桌面应用中的 pull request Overview 页面开始，以 issue 中描述的浏览器行为作为参考。跟踪链接 issue 的表示方式以及应用如何打开 issue，然后添加一种从 PR 导航到其链接 issue 的方式。当存在链接 issue 时按钮可用，并且能在应用中打开该 issue，即表示完成。

由索引模型根据 Issue 内容生成。
