Add driver location to description for method 2

[BerndGaykema]

I bought your 2nd choice (3-pack) but when connecting the board to the Win-10 PC there was no COM-port.
After searching for over an hour I found the following site: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads.

And yes, the latest universal driver for Windows did the trick: I now have COM-port 4 and flashing was successfull.

Thank you very much for making this local hub available. Athom has to improve the Bluetooth radio in Homey Pro (2023) a lot before it covers the same area as the litle Switchbot Remote.
