ci: set release environment for publish job

[marandaneto]

💡 Motivation and Context

The release workflow failed while publishing PostHog@2.8.0 because NuGet trusted publishing rejected the OIDC token:

Environment mismatch for policy 'posthog-dotnet': expected 'Release', actual ''

The publish job requested id-token: write but did not declare the Release GitHub environment, so the token did not include the environment claim required by the NuGet policy.

💚 How did you test it?

• Parsed .github/workflows/release.yml successfully with PyYAML.

📝 Checklist

• I reviewed the submitted code.
• I added tests to verify the changes.
• I updated the docs if needed.
• No breaking change or entry added to the changelog.

If releasing new changes

• Ran pnpm changeset to generate a changeset file

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

An agent investigated the failed GitHub Actions run, identified the missing release environment on the publish job, and made the smallest workflow change needed for NuGet trusted publishing to receive the expected environment claim.
