[xy] Set repo_path when syncing trigger configs.

[wangxiaoyou1993]

Description

Set repo_path when syncing trigger configs so that triggers.yaml of the same pipeline in multi-dev environment don't affect each other.

How Has This Been Tested?

• Tested with triggers.yaml in a pipeline. Before the fix, there's no repo_path associated with the PipelineSchedule. After the fix, the repo_path is added the PipelineSchedule db models.

tested it in multiple project platform as well (note: the trigger name needs to be different in different project)

• before fix
  
• after fix
