Grammar fixes (#7441)

Added a bunch of missing "the"s and "a"s mostly. Didn't change any of the coding examples or the meaning of this example. Great example though, thanks.

-Please note that you may simplify this sketch by removing function ``monitorWiFi()`` and putting inside ``loop()`` only ``wifiMulti.run()``. ESP will still reconnect between configured access points if required.

-As shown in above example, reconnecting between access points takes time and is not seamless. Therefore, in practical applications, you will likely need to monitor connection status to decide e.g. if you can send the data to external system or should wait until connection is back.
