Add link to documentation for Bluetooth Workflow #371

I've been trying to test connecting in the Bluetooth Workflow using Windows.

I found these instructions: https://learn.adafruit.com/wirelessly-code-your-bluetooth-device-with-circuitpython/device-setup

I noticed the caveats that using Windows is problematic. Here are some ideas for improving the user experience:

1. It would be helpful to link the documentation link above from the workflow dialog.

2. When reviewing the docs, I also noticed these issues in the docs:

• It might also be helpful to include the tip about windows connection if the app detects it's running on windows, but the tip didn't quite match my experience)

• On my Feather ESP32-S3, you hit the bootsel button when the blue button blinks, not reset to set it into advertising mode.

• After connecting for the first time, I got a popup: TypeError: e.watchAdvertisements is not a function That went away once I enabled the Chrome Experiment 'Use the new permissions for Web Bluetooth' even though I'm running the latest Chrome:

Although I've sucessfully connected, other functions haven't worked for me yet. Still working on it.
