[CI] [tensornet] Attempt to set target causes fatal error in some OS environments

[khalatepradnya]

• The tensornet and tensornet simulators may not be available in the CI environment. A Python test which attempts to check the availability as shown below, causes the Validate wheel and Validate installer stages to crash.

(Added following in python/tests/kernel/test_sample_kernel.py)

@pytest.mark.parametrize("target", [
    'density-matrix-cpu', 'nvidia', 'nvidia-fp64', 'nvidia-mqpu',
    'nvidia-mqpu-fp64', 'qpp-cpu', 'tensornet', 'tensornet-mps'
])
def test_simulators(target):
    """Test simulation on all available simulation targets."""

    def can_set_target(name):
        target_installed = True
        try:
            cudaq.set_target(name)
        except RuntimeError:
            target_installed = False
        return target_installed

    if can_set_target(target):
        test_simple_sampling_qpe()
        cudaq.reset_target()
    else:
        pytest.skip("target not available")

    cudaq.reset_target()

Runs: locally in dev-image. Validate wheel stage

• runs successfully on Fedora (arm64 and amd64), Debian (amd64)
• crashes on Ubuntu (amd64), RedHat (amd64), OpenSuse (amd64)

Validate installer stage

• only works on Debian (amd64)
• crashes on Ubuntu (arm64 and amd64), RedHat (arm64 and amd64), OpenSuse (amd64), Fedora (arm64 and amd64)
