Subject: [PATCH] Fix JsonType to use `Any` for Mapping values

The recursive JsonType definition used Mapping[str, "JsonType"], which
caused mypy to reject valid dict subtypes like dict[str, object] or
dict[str, Collection[str]] due to mypy's invariance handling of
recursive Mapping types.

The fix replaces the recursive Mapping value type with Any, matching
how Python's json.dumps actually accepts any serializable value.

Fixes #7443
