Use PAT_TOKEN instead of GH_TOKEN to automate PR

[yue9944882]

Currently it's a pain to manually release new versions. The following is an example of what we manually did for releasing 24.0.0: > #4054 (comment)

1.33 Model regeneration PR: https://github.com/kubernetes-client/java/pull/4056

Cut release branch release-24

1.33 Model regeneration PR for legacy branch: https://github.com/kubernetes-client/java/pull/4059

Cut release branch release-legacy-24

Run release workflow for release-24: https://github.com/yue9944882/java/actions/runs/15217107346

Run release workflow for release-legacy-24: https://github.com/yue9944882/java/actions/runs/15218963083

Release 24.0.0 PR: https://github.com/kubernetes-client/java/pull/4062

Release 24.0.0-legacy PR: https://github.com/kubernetes-client/java/pull/4063

Publish 24.0.0 tag

Publish 24.0.0-legacy tag

This is due to the default github action token losing the access for creating pull requests via the workflow. As a workaround, this PR allows the release job to use PAT_TOKEN which is my personal account's token that only contains PR creation permission so the release process can be automated again.

I don't love using personal access tokens for this, but it's an ok work around for now. Let's make sure we continue to keep the scope limited to PR creation.
