Steam Authentication Improvements

We've released a new Steam authentication endpoint with improvements to both flow and stability.

The improvements feature 2 changes:

• A simplified authentication flow, combining verification with starting a session into a single endpoint.
• New internal retry logic, which will automatically retry failed requests to the Steam Servers.

If you're using the Unity or Unreal SDKs, you do not need to make any changes, if you're using VerifyPlayerAndStartSteamSession to start sessions.

For people doing verification and session separately, the old endpoints will keep working, but we recommend switching to the new endpoint for better performance.

The new endpoint is available at POST /game/session/steam.
