[PORT] Fix git error handling (gitea#32401)

Browse source 
---
Conflict resolution: Trivial, for `repo_attributes.go` move where the
`IsErrCanceledOrKilled` needs to happen because of other changes that
happened in this file.

To add some words to this change: It seems to be mostly simplifying the
error handling of git operations.

(cherry picked from commit e524f63d58900557d7d57fc3bcd19d9facc8b8ee)
