add rp2040 support to the wizard

[fodfodfod]

Describe the problem you have/What new integration you would like

Create config files for rp2040 boards with the ESPHome wizard

Please describe your use case for this integration and alternatives you've tried:

Simplifying the creation of new firmware yaml files for rp2040 with the wizard because the dashboard is not available through the container version of home assistant. It is possible to use the wizard and then change the board to rp2040 but this allows you to create it directly from the wizard.
