[ci] Update create pull request script in github actions (#11350)

I misunderstood the what the create-pull-request github action does. Its mechanism is to work with branch diff between base and target-branch and squash and push the change to into the target-branch to create a pr against the current working directory. It is designed to auto sync the current work directory with changes from other branches.

In our use case, the branch has been prepared through the branch_for_batch_release script, so we don't want the github action to do the squashing and rehash the commit. Instead, we just need to use a simple gh cli to create a pr.

## Pre-Review Checklist

**Note**: The Flutter team is currently trialing the use of [Gemini Code Assist for GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code). Comments from the `gemini-code-assist` bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.

[^1]: Regular contributors who have demonstrated familiarity with the repository guidelines only need to comment if the PR is not auto-exempted by repo tooling.
