[IR] Fix an error when checking for float8_e4m3fnuz type in ir.Tensor

[justinchuby]

The float8_e4m3fnuz type was mistaken with float8_e4m3b11fnuz, which is a different type: https://github.com/jax-ml/ml_dtypes#float8_e4m3b11fnuz

PR Overview

This PR fixes an error in the type-checking logic for ir.Tensor by correcting an incorrect reference to the float8 type.

• Corrects the mistaken type from ml_dtypes.float8_e4m3b11fnuz to ml_dtypes.float8_e4m3fnuz.
