Feature request: erase previous comments when alt-text is filled

[scarf005]

hi, i stumbled across this bot while opening an issue reqeust on typescript-eslint/typescript-eslint#9699.

Status quo

• the bot will run on every issue body creation/modification, and will add a new comment on alt-text violation.
• even after all the alt-text violation is fixed, the comments are still there unmodified.

The issue

• it feels awkward and crowded to keep having the comments even after all the alt-text issues are fixed.
• in this screenshot, the second comment is automatically hidden (due to duplicate entry?), but the first isn't.
• this may be confusing considering the alt-text is now fixed.

The suggestion

it'd be great to have an option to erase/hide previous accessibility-alt-text-bot comments when there's no alt-text issue found.
