Overview of the Issue

Since the GitHub REST API ListComments endpoint doesn't expose the isMinimized attribute, on each Atlantis command, we sequentially minimize Atlantis comments, even if they are already minimized. This process can take significant time, proportional to the number of existing Atlantis comments within a pull request.

We might consider switching to the GitHub GraphQL API for listing comments, as it exposes the isMinimized attribute. This would help avoid performance degradation by minimizing only the last Atlantis comment, as opposed to processing all comments sequentially.

Relevant code is here

I'd like to work on the fix for this.

Reproduction Steps

• Use Github
• Enable --hide-prev-plan-comments
• Run many Atlantis commands in the same pull request and notice that the full cycle takes increasingly more time on each iteration
