Documentation inaccuracy: ExtensionCadence default is 1/3 of MinValidityTime, not Expire

[lhawick]

At this page in the documentation, it states that the ExtensionCadence default is 1/3 of the Expire parameter.

However, this is not accurate. In the RedisDistributedSynchronizationOptionsBuilder (source), the value is actually set to 1/3 of MinValidityTime.

This discrepancy could confuse users relying on the docs for configuration. Could the documentation be updated to reflect the correct behavior?
