withings: don't store the webhook URL in the state. (#69191)

The webhook url should be calculated at startup, not stored in the state
as otherwise a change in network requires re-configuring the integration
from scratch.

This is particularly important as external network configuration might
change when moving HA between networks, and it's not obvious it needs
to be re-added just for this.
