Update ReadOnlyEntityOptions typing

[cdce8p]

Proposed change

The Mapping class does not provide a __(r)or__ operator for assistant_options | {key: value}, this should be a dict typing. Additionally, even with ReadOnlyDict this will return a dict. This isn't an issue as it's passed through a converter with

core/homeassistant/helpers/entity_registry.py

Lines 177 to 179 in bf41167

	options: ReadOnlyEntityOptionsType = attr.ib(
	default=None, converter=_protect_entity_options
	)

core/homeassistant/helpers/entity_registry.py

Lines 143 to 149 in bf41167

	def _protect_entity_options(
	data: EntityOptionsType | None,
	) -> ReadOnlyEntityOptionsType:
	"""Protect entity options from being modified."""
	if data is None:
	return ReadOnlyDict({})
	return ReadOnlyDict({key: ReadOnlyDict(val) for key, val in data.items()})
