Required prerequisites

• Consult the security policy. If reporting a security vulnerability, do not report the bug using this form. Use the process described in the policy to report the issue.
• Make sure you've read the documentation. Your issue may be addressed there.
• Search the issue tracker to verify that this hasn't already been reported. +1 or comment there if it has.
• If possible, make a PR with a failing test to give us a starting point to work on!

Describe the bug

When I pass a list[list[int]] to a cudaq kernel, I get the following error:
RuntimeError: error: Cannot infer CUDA-Q type from provided Python type (!cc.stdvec<!cc.stdvec>)
I didn't expect this, since in the documentation there are examples where this type is passed to a kernel.

Steps to reproduce the bug

import cudaq
@cudaq.kernel
def test_list_list(a: list[list[int]]):
    qc = cudaq.qvector(3)
    j = 0
    for i in a:
        if i[0] == 1:
            x(qc[j])
        j += 1
    mz(qc)
 
print(cudaq.sample(test_list_list,[[0,1],[1,0],[1,0]]))

Expected behavior

I expect to get the output {'011' : 1000}.

Is this a regression? If it is, put the last known working version (or commit) here.

Not a regression
