HA2025.10 warns about `object_id` in MQTT discovery payload

[hmmbob]

Describe the bug
HA 2025.10 warns abut a deprecated discovery payload for every entity:

The configuration for entity text.smartevse_6360_ledcolorcustom uses the deprecated option `object_id` to set the default entity id. Replace the `"object_id": "SmartEVSE-6360-LEDColorCustom"` option with `"default_entity_id": "text.SmartEVSE-6360-LEDColorCustom"` in your published discovery configuration to fix this issue, or contact the maintainer of the integration that published this config to fix this. This will stop working in Home Assistant Core 2026.4

More info: home-assistant/core#151775

I'll draft a PR with a similar fix as in zigbee2mqtt: Koenkk/zigbee2mqtt#28560
