ci: remove unused release workflow permissions

[marandaneto]

💡 Motivation and Context

The release job has Actions write and OIDC permissions without a corresponding operation.

Remove actions: write and id-token: write from the release job. Keep contents: write for GitHub release creation. Hex and GitHub App authentication stay unchanged.

This follows the permissions audit prompted by PostHog/posthog-js#4889. Read-only workflow defaults are unchanged. This does not change build/publish isolation or restrict separate GitHub App tokens.

💚 How did you test it?

• Actionlint passed for the original and updated release workflow.
• Parsed the original and updated YAML and verified that only the listed permission keys changed. Triggers, steps and job dependencies are unchanged.
• git diff --check passed.
• Reviewed the pinned action contracts and retained the permissions used by the release steps. No live release was run.

📝 Checklist

• I reviewed the submitted code.
• I added tests to verify the changes. No SDK tests apply to this permissions-only change.
• I updated the docs if needed. No documentation change is needed.
• No breaking change or entry added to the changelog.

If releasing new changes

No package release or changeset is needed.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Implemented with Pi and delegate agents using file tools, Git, GitHub CLI, Python/PyYAML and actionlint. The parent agent reviewed the final diff. Work was limited to removing unused workflow permissions in a dedicated worktree. Autoreview was skipped because this diff contains only GitHub workflow permission administration. No session transcript was published. Human review is required.
