Inaccurate: ....to validate your commit messages when you `setup` your AppFlowy repo.
Accurate: ....to validate your commit messages when you `set up` your AppFlowy repo.

Explanation: `setup` is a noun and `set up` is a verb. In this context it should be a verb.

Open documentation/software-contributions/conventions/git-conventions.md and inspect line 9. Change the verb “setup” to “set up” in the sentence about validating commit messages, then review the surrounding text to confirm the correction is clear.
