feat: retry plugin

[whilefoo]

resolves #66

[0x4007]

Seems odd to use + to coerce into a number instead of using Number()

[whilefoo]

@gentlementlegen I think something changed and now tests are failing.

It changed from CONTRIBUTOR to COLLABORATOR so that's why rewards are different.

Why are we testing on real Github issues, it seems prone to bugs like these? Is there any particular reason why we can't mock github issues and comments? I still haven't figured out how to run tests on my local machine so I have to rely on Github actions :D

[gentlementlegen]

@whilefoo It must be because I figured out yesterday that if a user has the organization in private, the bot would consider that you are a contributor and not a collaborator. So now that I made it public so I became a COLLABORATOR.

These tests were not mocked somehow hence the difference now. You can see in the conflicts that I made the required changes to mock all of these so this should not happen anymore.

PS: sorry for the conflicts

[gentlementlegen]

@whilefoo The logic works however the posted message is wrong (test run here) so you might want to serialize the object.

Seems to work fine: Meniole#6 (comment)
