false positive bad-argument-type with dict

### Describe the Bug

NOTICE: same is value used in both `invalid()` and `valid()`.

```python
from collections.abc import Mapping
from pydantic import BaseModel
from pydantic.types import JsonValue

class EscalationChainState(BaseModel):
@classmethod
def regen_text(cls, meta: Mapping[str, JsonValue]) -> None: ...

def invalid() -> None:
meta = {"owner": {"name": "Alice"}, "zone": {"name": "B2"}}
EscalationChainState.regen_text(meta) # pyrefly: ignore [bad-argument-type]

def valid() -> None:
EscalationChainState.regen_text(
{"owner": {"name": "Alice"}, "zone": {"name": "B2"}}
)
```

possibly related to #3160
