[ENHANCEMENT] get debugpy debuggerpackagepath from ms-python.debugpy extension

[d-biehl]

The the debugger of the ms-python.python extension is deprecated, RobotCode switches to the new debugpy extension, but this extension does not exports an api to get the path to the python debugpy package. I would assume that api is implemented some times or it is integrated into the pyhton extension api, let's see.

the workaround at the moment is to use the debug.debuggerpackagepath from the ms-python.python extension

There is a ticket in the ms-python.debugpy microsoft/vscode-python-debugger#194

and a new ticket:

microsoft/vscode-python#23032
