Duplicate comments showing up in pull request page

Jenkins and plugins versions report

I am using the pullRequest.comment("comment") method to add a comment on the GitHub PR page. From the Jenkins side I am only calling this method once during the build, but on the GitHub side it is adding same comment two times. I have added the output on the "Actual Results" section.

I have also printed the comment id from the Jenkins, and compared the comment id from the GitHub page. In all cases the second comment's id is showing in the Jenkins log, but no info is available about the first comment present in the GitHub side.

Environment

```text Jenkins: 2.332.3 OS: Linux - 5.10.112-108.499.amzn2.x86_64 --- git:4.11.3 git-client:3.11.0 git-server:1.11 github:1.34.3 github-api:1.303-400.v35c2d8258028 github-branch-source:1628.vb_2f51293cb_78 pipeline-github:2.8-138.d766e30bb08b pipeline-github-lib:36.v4c01db_ca_ed16 ```

What Operating System are you using (both controller, and any agents involved in the problem)?

Amazon Linux 2. No agents are involved. Running builds on the controller itself.

Reproduction steps

Used the def comment = pullRequest.comment("comment") method to add the comment.

Expected Results

Only one comment should be added on the GitHub page when I used the pullRequest.comment method only once.

Actual Results

Two duplicate comments are added in the GitHub PR page. Please find below,
