[flakybot] Bot reopens issues that were closed due to being fixed

[clee2000]

Example https://togithub.com/pytorch/pytorch/issues/131081#issuecomment-2259257471 (the example is from a commit that was right before the fix got merged)

While the rerun job will likely go close this after it finds that no longer fails, it is confusing for devs when they fix and issue and then the bot claims there's another failure
