Improv implementation is not accroding to web spec

[dz0ny]

The problem

Improv implementation is not according to web spec, when trying to use https://www.improv-wifi.com/ the error in the console is Firmware not according to spec, missing capability support. Looking at the code it tries to read from it but the service only supports write.

https://github.com/esphome/esphome/blob/dev/esphome/components/esp32_improv/esp32_improv_component.cpp#L33

           try {
                const e = await t.getCharacteristic("00467768-6228-2272-4663-277478268003")
                  , i = await e.readValue();
                this._improvCapabilities = i.getUint8(0)
            } catch (t) {
                console.warn("Firmware not according to spec, missing capability support.")
            }

Additional information

When using https://googlechrome.github.io/samples/web-bluetooth/characteristic-properties.html?service=00467768-6228-2272-4663-277478268000&characteristic=00467768-6228-2272-4663-277478268003

I can see that service has only write enabled
