Add agents.md guideline for using ASD-STE100 in documentation

This add the `espradio` build tag to all ESP32C3,
ESP32S3, and ESP32 boards, since they all have support
for wireless communication using espradio. This
just makes it to people do not have to remember to use
the build tag, the same as we have done with both
`ninafw` and `cyw43439` build tags.
