Frozen time does not apply on UUIDs

With the following code:

```py
@pytest.fixture
async def some_function(
frozen_time: freezegun.FreezeGun
):
raise ValueError(datetime.now(timezone.utc), extract_timestamp_from_uuid7(str(uuid7())))
```

We see that the `datetime.now` is really frozen, but not the uuid:

```
ValueError: (FakeDatetime(2012, 1, 14, 0, 0, tzinfo=datetime.timezone.utc), FakeDatetime(2025, 5, 21, 12, 48, 51, 900000, tzinfo=datetime.time
zone.utc))
```
