BUILD: Update numpy requirement to >=1.20.0,<2.2

[SMoraisAnsys]

As title says. Changes include:

• use cdouble instead of the long deprecated complex_ when defining dtype with numpy functions;
• switch from pytomlpp to toml;
• update ci workflow to not use caching.

The reason for the switch in toml dependency is related to two facts:

1. There is a problem when combining Linux + numpy>=2.0+ pytomlpp. Indeed, in Linux, we end up loading the libPyDesktopPlugin.so file (see

   pyaedt/src/ansys/aedt/core/generic/grpc_plugin_dll_class.py

   Line 292 in c098962

   AedtAPI = PyDLL(AedtAPIDll_file)

   ) and it seems to be interfering with how pytomlpp works as we are no longer able to load a TOML file. See
   
2. toml does provide read and write capabilities while tomli (a more standard package) does only provide read capabilities.

---

NOTE: AFAIK mono needs to be reachable (hence the current LIBRARY_PATH extension) for pyedb to be able to load EDBWrapper. Otherwise, instantiating an Edb object will raise an exception. This can be avoided if one installs mono manually but I'm not chaning this as it is probably a standard work around used by our users. At some point, it would be wise to remove dotnetcore/dotnetcore2 and ensure that dotnet + mono are installed if required.

@svandenb-dev This PR won't be able to pass until a new release of pyedb.

To be added after success of the CI workflow.

@Samuelopez-ansys Let me know if you want to remove the changes that are currently added here about using cache in CICD. I had to remove it to ensure that numpy>=2. got used otherwise a local numpy==1.Y.Z was used.

Seems like the fix is not working when adding back osmnx and merging main. I need to double check if this is related to using numpy<2 due to osmnx.
