import problem with qiskit conversion

[GuusAvis]

Issue Description

I want to use mitiq to convert a circ circuit to a qiskit circuit, but the function I find in the documentation gives me an error. Importing the relevant module separately does fix it though.

The error I get is the following:

{
	"name": "AttributeError",
	"message": "module 'mitiq.interface' has no attribute 'mitiq_qiskit'",
	"stack": "---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[5], line 1
----> 1 mitiq.interface.mitiq_qiskit.conversions.to_qiskit(ct)

AttributeError: module 'mitiq.interface' has no attribute 'mitiq_qiskit'"
}

How to Reproduce

import mitiq
ct = mitiq.benchmarks.generate_random_clifford_t_circuit(5, 3, 3, 3)
mitiq.interface.mitiq_qiskit.conversions.to_qiskit(ct)

Expected behavior

This codes does implement the expected behavior:

import mitiq
import mitiq.interface.mitiq_qiskit.conversions as conv
ct = mitiq.benchmarks.generate_random_clifford_t_circuit(5, 3, 3, 3)
qiskit_ct = conv.to_qiskit(ct)
