PR description is not updated for forked PR.

[venkuppu-chn]

The action work well when I tried to create a branch in the repository and do raise the PR. However, I tried the same action for the forked PR, it throws the following error even though the GITHUB_TOKEN has write permission in the Github workflow. Please help me to understand this issue.

Error Message:
