Add `Copy Link` to each comments on Pull Request view

Like we copy the comment's link from the comment box, it would be great if it could do the same thing on the extension's webview.

You should already be able to do this:

@alexr00 Hi, thank you for your reply.

On the Pull Requests view and on the comment box in each files, yes, you are right, I can copy the comment's link.
But unfortunately, on the Pull Request top view, I don't see anything that I can copy the comment link.

In the following PR (#6278), I can find only Quote Reply. If we can copy the URL from here, that would be great.

In detail, I don't see any copy link button here:
