ci: use GitHub App for Release Please

[jbeckwith-oai]

Summary

• mint a repository-scoped installation token for the openai-sdks GitHub App from the existing release environment
• pass that token to Release Please and disable the release job's built-in GITHUB_TOKEN permissions
• preserve the existing RubyGems publish and retry flow

Why

Release Please currently authenticates with GITHUB_TOKEN. Events created with that token do not normally start downstream workflows. A GitHub App installation token triggers the normal push and pull-request workflows for the generated release branch.

This is the Ruby equivalent of openai/openai-python#3577. Ruby does not have Python's manual release-PR workflow-dispatch workaround, so no CI dispatch cleanup is needed here.

Repository configuration

• existing environment: release, restricted to main with no required-reviewer gate
• existing environment variable: OPENAI_SDKS_APP_CLIENT_ID
• required before merge: add the environment secret OPENAI_SDKS_APP_PRIVATE_KEY (the secret is not currently present in the Ruby repository's release environment)

Validation

• actionlint v1.7.7 .github/workflows/create-releases.yml
• Ruby YAML parse
• git diff --check
• thermo-nuclear code quality review

Pull request overview

Updates the release automation workflow to authenticate Release Please using a GitHub App installation token (minted from the existing release environment) instead of GITHUB_TOKEN, so that release-branch pushes and release PR events can trigger downstream workflows as expected.

Changes:

• Add a step to mint a repository-scoped GitHub App installation token from the release environment.
• Pass the GitHub App token to googleapis/release-please-action and disable default GITHUB_TOKEN permissions for the release job.
• Preserve the existing publish job behavior (RubyGems publish + retry flow unchanged).
