A few suggestions to make PR comments easier to use.

First it would be to clean up outdated comments. If a PR goes through several iterations the comment thread get's long. Doing something like this action (maheshrayas/action-pr-comment-delete) does would help keep the SPAM in check.

Second, it would be nice if the tables with the changes were in a <details> <summary> block that was shrunk down by default. This action does something like that with diffs int128/comment-action.

Third, it would be nice if there was a bit more detail about what specifically changed with each resource when you run speculative plans so you don't have to read the plan log to understand the change details.
