freertos: Update the docuementation of the ulBitsToClearOnEntry parameter in xTaskGenericNotifyWait() function.

The description of how the xTaskGenericNotifyWait parameter is handled in the
xTaskGenericNotifyWait() function was inaccurate.

In this commit, the description was updated to match the implementation of xTaskGenericNotifyWait().
