blenderproc run failed when use --custom-blender-path

[arc130]

Describe the issue

I had downloaded the blender on browser. However, I got error with blenderproc run ./quickstart.py --custom-blender-path D:/blender-3.3.1-windows-x64/

Traceback (most recent call last):
  File "D:\ProgramData\miniconda3\envs\blenderproc\lib\runpy.py", line 196, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "D:\ProgramData\miniconda3\envs\blenderproc\lib\runpy.py", line 86, in _run_code
    exec(code, run_globals)
  File "D:\ProgramData\miniconda3\envs\blenderproc\Scripts\blenderproc.exe\__main__.py", line 7, in <module>
  File "D:\ProgramData\miniconda3\envs\blenderproc\lib\site-packages\blenderproc\command_line.py", line 149, in cli
    blender_run_path, major_version = InstallUtility.make_sure_blender_is_installed(custom_blender_path,
  File "D:\ProgramData\miniconda3\envs\blenderproc\lib\site-packages\blenderproc\python\utility\InstallUtility.py", line 239, in make_sure_blender_is_installed
    blender_run_path = os.path.join(blender_install_path, blender_version, "blender")
UnboundLocalError: local variable 'blender_version' referenced before assignment

I found the blender_version was defined in condition if custom_blender_path is None: at line 96, which indicated there is something wrong at platform "win32"

OS:
Windows 10

Minimal code example

Files required to run the code

Expected behavior

Successful run script

Hey @arc130,

thanks for the issue report. This should already be fixed by #972 and will be part of the next version.
Until then, you could use the current blenderproc state on the main branch.
