NimbusJwtDecoder's default RestOperations now respects the JDK's
sun.net.client.defaultConnectTimeout/defaultReadTimeout system properties,
falling back to 30 seconds instead of the previous 500 milliseconds,
matching JwtDecoderProviderConfigurationUtils's existing behavior.
Also documents this default and the RestOperations override in the
reference guide and migration guide (the reference guide's existing
"Configuring Timeouts" section already claimed 30 seconds -- it's been
inaccurate since the 500ms default shipped and is now correct again), and
documents providing a custom JwtDecoderFactory<ClientRegistration> for
OAuth2 Login's ID Token decoding.
