fix: T-Echo auto-detection (vscode)

[mverch67]

This is a minor dev environment fix to allow T-Echo serial port auto-detection in vscode. Currently, when uploading the firmware and no port is selected a weird "eink" error message appears.

$ lsusb | grep Echo
Bus 005 Device 070: ID 239a:002a Adafruit T-Echo v1

This HW ID was missing in boards/t-echo.json

Hey @mverch67, I encountered this error with the newest alpha firmware available.
platformio device list output:

/dev/cu.Bluetooth-Incoming-Port
-------------------------------
Hardware ID: n/a
Description: n/a

/dev/cu.usbmodem1101
--------------------
Hardware ID: USB VID:PID=239A:0029 SER=05EABFEB5F625160 LOCATION=1-1
Description: T-Echo v1

As you can see, the PID is equal to 0x0029. After adding this pair to boards/t-echo.json, I was able to upload new firmware to my device.

Same here T-Echo v1 with 239A:0029.
