[Suggestions] Enhance PR review experience in Copilot Workspace

[juliamuiruri4]

I've played around with Copilot Workspace for a while now and this feature has really transformed how I make contributions on GitHub - Big thank you to the team!

After using the feature to respond to a PR review, I'm noting here a few (minor) additions that I think would significantly improve the overall user experience.

Include comments.

Comments are key components in a PR Review to suggest improvements/ideas, flag issues, or ask clarifying questions. With the current experience, I'm only able to see and act on code changes in diff, but any comment without the suggested code isn't shown in the UI. I thought I had implemented all suggestions but luckily, I manually spotted some comments just before signing off and acted on them.

It would be a nice improvement to be able to switch between the individual comments on the PR as part of a review.

And with comments, I think providing a way to respond to them would be more efficient.

Add scroll to view changes live for each suggestion.

Since the UI allows viewing and applying one code suggestion at a time, it would be nice to synchronize the selected suggestion with the exact part of the file with the code to be modified. (Just in case I want to be really really sure that by clicking 'Apply', the correct changes were made and that nothing else got altered)
