docs(anonymous-sessions): handle session expiry error in getTokenSilently example

[yogeshchoudhary147]

Updates the getTokenSilently example to show how to catch AnonymousSessionError for session_expired and invalid_session_token and recover by calling createSession(), following the throw-on-expiry behavior shipped in v2.28.2.

Summary by CodeRabbit

• Documentation
  • Updated the anonymous access-token example to create a new session and retry the token request when a session is expired or invalid.
  • Clarified that other errors are rethrown, cached tokens may be reused, and tokens are renewed after they expire.
  • Removed the separate statement about transparent renewal.

Review details

Systems and components

• observed — EXAMPLES.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in EXAMPLES.md: The anonymous-token example now documents cached-token use and renewal, and catches AnonymousSessionError from getTokenSilently(). It starts a new session only for session_expired or invalid_session_token and rethrows other errors. The prior example made the token request and API call without error handling and described renewal as transparent.

- Line 2243: Update the callApi example around anonymous.createSession() so
that, after handling a session_expired or invalid_session_token error and
creating a new session, it retries getTokenSilently() and continues to fetch the
requested API resource with the retrieved access token. Preserve propagation of
other errors.
