pyproject.toml doesn't support Redis 8

Hi,

Cheers for this great project!

In [pyproject.toml](http://github.com/redis/redis-om-python/blob/main/pyproject.toml)  - 
```
[tool.poetry.dependencies]
python = ">=3.8,<4.0"
redis = ">=3.5.3,<7.0.0"
```

Is Redis 8 not officially supported?


Thanks,
Eli
