feat(debian): CC33x1: Update docs to use NetworkManager

Update the CC33x1 "HowTo Guide" to use NetworkManager service and its
nmcli tool for connecting to wifi, instead of using the current method
of cc33xx-target-scripts.

The scripts are required only in Arago, which is a custom distribution.
But on Debian, we should use Debian's default way of managing wifi.

+   TI's Debian SDK uses NetworkManager to connect to wifi. To connect, ensure that NetworkManager.service is running
+   with the following command:
+
+   .. code-block:: console
+
+      systemctl status NetworkManager.service
+
+   It should show status as "active". If it isn't active, activate it by running the following:
+
+   .. code-block:: console
+
+      systemctl restart NetworkManager.service
+
+   Then, to actually connect to wifi, use `nmcli` as follows:
+
+   .. code-block:: console
 
-        cd /usr/share/cc33xx
-        bash ./sta_start.sh
-        bash ./sta_connect.sh -s WPA-PSK -n <SSID> -p <PASSWORD>
-        udhcpc -i wlan0
+      nmcli device wifi connect "<SSID>" password "<password>"
