fix(valkey): keep basedpyright arg-type budget green after main merge

The from_url client's return type is unknown under the types-redis 4.6
stubs, so raw_result reaches _to_response as an unknown-typed argument.
Suppress reportUnknownArgumentType on those two returns, matching the
existing stub-gap ignores on the same calls. No runtime change.
