bug: Auto-comment workflow creates duplicate comments under certain conditions

[jihoon-seo]

This repo currently has a workflow enabled that adds the comment "Wait, please do not proceed with this yet." when a PR with the "hold" label is added.

• https://github.com/cncf/glossary/blob/main/.github/workflows/auto-comment.yml
• https://github.com/cncf/glossary/blob/main/.github/auto-comment-config.yaml

However, when I added the "hold" label to my PR (#3619), "github-actions" (a bot) added 15 duplicate "Wait, please do not proceed with this yet."

To find out why, I looked at https://github.com/cncf/glossary/actions/workflows/auto-comment.yml. When I added the 'hold' label, I also removed the 'lang/xx' labels that were incorrectly attached at the same time. This caused the workflow to be executed separately for each 'lang/xx' label removal event.

This behavior could be prevented by slightly modifying the workflow execution conditions in https://github.com/cncf/glossary/blob/main/.github/workflows/auto-comment.yml.

If anyone would like to take on this task, please comment on this issue to express your interest and open a pull request targeting the main branch.
I encourage anyone interested to contribute.

Hi! I'd like to work on this issue. I'll modify the workflow execution conditions in auto-comment.yml to only trigger when the 'hold' label is specifically added. Please assign this to me!
