REFACTOR: Loading dotnet runtime

[SMoraisAnsys]

Description

To improve compatibility with system libraries in Linux, the Python package dotnetcore2 should be removed from PyAEDT's dotnet installation target. Indeed, the embedded version of .NET associated to dotnetcore2 is old and has incompatibilities with recent versions of openssl such as the one installed by default in Ubuntu 22.04.

This PR propose to add this modification to the breaking changes of release v1.0 and, in the mean time, to allow users to:

• use a .NET runtime that they have installed instead of the one embedded in dotnetcore2
• fallback to the dotnetcore2 approach if no .NET runtime is detected / provided through environment variable (DOTNET_ROOT).

Note

Tests implementation differs from pyedb since pyaedt has a filterwarnings option for pytest.

Hi @AlfVII @clguenthe I'm pinging you because, following a previous issue, I had the feeling that you might still be using PyAEDT with dotnet. If that's the case, could you give a try at this PR to check that it suits you well ? If something is wrong, please let me know !
