DogFood: Use OpenDevin to review PRs

[li-boxuan]

What problem or use case are you trying to solve?

It would be nice if we could let OpenDevin review PRs in OpenDevin repo. Inspired by https://github.com/OpenDevin/OpenDevin/issues/1067.

Describe the UX of the solution you'd like

No UX is needed. We need a GitHub workflow file.

Do you have thoughts on the technical implementation?

Reviewing PRs sounds easy, but in some sense, it's harder than creating a PR. To review a PR, the agent essentially needs to:

1. Understand the patch
2. Fix/Modify the patch
3. Verify the patch works
4. Suggest the updated patch

Of course, at the moment, we can simply let the agent review the patch and post a single review comment. Eventually it shall be able to submit review at appropriate lines, and/or even Add a suggestion (one-liner code changes that can be directly applied on GitHub GUI) directly.

Additional context

I am working on this. Will come up with a preliminary version soon.
