CI: Temporary removal of PyAEDT dotnet tests

[SMoraisAnsys]

Following #986, this PR aims at avoiding the tests that are currently failing when releasing.

For visibility and future reference, here is a mini reproducer of the failure within the VM

import os
from ansys.aedt.core.generic.grpc_plugin_dll_class import AEDT
os.environ["DesktopPluginPyAEDT"] = "/opt/AnsysEM/v242/Linux64/PythonFiles/DesktopPlugin"
AEDT(os.environ["DesktopPluginPyAEDT"])

from pythonnet import load
load(
    "coreclr",
    runtime_config=str("/usr/share/dotnet/sdk/6.0.428/dotnet.runtimeconfig.json"),
    dotnet_root=str("/usr/share/dotnet")
)

Note that removing the first 4 lines of the previous snippet allows to load coreclr correctly.

Closing as it shouldn't be required anymore once ansys/pyaedt#5673 is merged.
