I would like to be able to remove reactions from a comment that I previously added.

Consider for example the following use case:
I have a long running job that results in a comment to PR.
When a new change is pushed, I want to indicate that I will update this comment by adding a reaction.
After the new comment content has been posted, I would like to remove this reaction again.

(This can of course as well be handled by adding text and replacing it later. If you want, I can think of a better use case 😂 )
