[Docker] Fix ml_dtypes downgrade issue introduced by TensorFlow (#17691)

The ml_dtypes>=0.5.1 was installed in the install python packages
script, but the tensorflow 2.18 installation later will uninstall the
ml_dtypes and install an old ml_dtypes version 0.4 instead. (https://ci.tlcpack.ai/blue/rest/organizations/jenkins/pipelines/tvm-docker/branches/main/runs/2062/nodes/50/steps/114/log/?start=0).
We can install ml_dtypes right after tensorflow.
