Bug

odmantic.model.is_type_mutable gives wrong result for Literal types.

Current Behavior

In [1]: from odmantic.model import is_type_mutable
In [2]: from typing import Literal

In [3]: is_type_mutable(Literal["x", "y"])
Out[3]: True

Expected behavior

Strings are immutable so the above should return False.

Environment

• ODMantic version: 0.9.2
• Pydantic version: 1.10.5
