Go template variable branch not worked in git directory generator

Checklist:

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

• While following the example for the git generator, cluster parameter is interpolated from the variable {{branch}}-{{path}}.
• It appears that the branch name of the current git repository is recognized, making it possible to deploy the application based on that branch.
• However, when actually configuring and deploying the applicationset with this setup, the {{path}} value is recognized correctly, but {{branch}} does not work as expected.

To Reproduce

• Deploy argocd v2.13 on k8s cluster
• Create git repository for applicationset
• Follow git generator and check the deployed application.

Expected behavior

• applicationset should recognize go template variable {{branch}}

Screenshots

Version

• argocd version: v2.13.2
