Support Numpy 2

Could you please support the use of label-studio with Numpy version 2? :-)

I was running into an issue with `uv add label-studio` in a virtualenv where I have a modern Tensorflow version installed:

Label Studio 1.17.0 requires numpy>=1.26.4,<2.0.0, but your TensorFlow installation (2.19.0) depends on ml-dtypes>=0.5.1, which in turn requires numpy>=2.1.0. These requirements are incompatible.

Maybe simply changing from `^` to `>=` here would allow the Numpy 2 usage?

For example for pandas I see you are already using `>=` here:
