feat: make copilot PR description adhere to PR template

[jooyoungseo]

Type: Feature Request

I appreciate the auto-PR description powered by Copilot in the settings:

{
  "githubPullRequests.pullRequestDescription": "Copilot"
}

I was wondering if this could adhere to PR template if that extis. That would be even more useful and a huge time saver.

a button for following the template would be nice, i suppose the button would include "follow the PR template" in the prompt
