[Python] Unable to validate environment

[alexandrul]

Sourcetrail: 2019.4.61
OS: Win 7 x64
Python: 3.8.0

After selecting a folder for the Python environment, the validation process looks only for scripts\python.exe, ignoring the perfectly valid Python instalation with a python.exe in the main folder.

For the moment I'm manually appending python.exe to the selected folder.

@alexandrul: Thanks for bringing this up. I think that the Python indexer should have a fallback that also checks if a valid environment can be found with the executable name appended to the provided path. This name may be different for different operating systems.
