evcc: integration should use template instead of type

[andig]

In evcc-io/evcc#20878 we see the following error:

details = "invalid vehicle type: skoda"

This is due to the skoda api being deprecated. evcc handles this by mapping deprecated apis to new versions:

template: enyaq
covers: ["skoda"]

This only works if the api calls use the templates. Instead of

type: skoda

the configuration sent should use

type: template
template: skoda

This will then internally enable evcc to use enyaq instead of skoda.
