Documentation: SG-Ready example needs calc offset of 2

[mbfoo]

Describe the bug

I am using the SG-Ready setup described here: https://docs.evcc.io/docs/devices/heating
After upgrading to 0.203.5, I got errors that the headpump is in dimm state.
I guess this is caused by evcc-io/evcc#20747.

It seems to be fixed by changing the getmode calc add value from 1 to 2 in the yaml.

Steps to reproduce

1. Use SG-Ready setup from https://docs.evcc.io/docs/devices/heating
2. Upgrade to 0.203.5
