This failed again, I replicated the same workflow in my fork, and it worked fine there, see: shravanngoswamii#1 (comment)

If this rerun also fails, then I think we need to add a permission in CI.yml:

permissions:
  contents: write
  pull-requests: write

I am not really getting the reason behind this failure, I tried different cases in my work and all worked fine there, see: shravanngoswamii#6, shravanngoswamii#1, I open PR from branch of base repo, from a fork of fork, from branch of base repo with latest commit from fork, etc...

Let's remove the CI changes from this PR, I will make another PR for fixing it in this repo.
Can you please add me in this repo so I can create a branches?

@yebai It's fixed now! It was just a permission issue, I added that in this PR itself!
