fix(nvs_console): use esp_stdio for console peripheral init

examples/storage/nvs/nvs_console/README.md

@@ -13,9 +13,13 @@ This example can run on any ESP32 family development board.
 
 The example can be configured through `menuconfig`:
 1. Enable/disable command history storage (`CONFIG_CONSOLE_STORE_HISTORY`)
-2. Configure UART parameters
+2. Select the console channel under **Component config → ESP-STDIO → Channel for console output**
+   (UART0 by default, or **USB Serial/JTAG** / **USB CDC** on supported chips)
 3. Configure console prompt color settings
 
+On chips with USB Serial/JTAG, set the channel to **USB Serial/JTAG Controller**,
+connect the USB cable to that interface, then monitor that port.
