make.bat template jumps to help block without first checking if sphinx is installed #10122
Description
Describe the bug
If you were to invoke make.bat, before installing sphinx, you would get the following error:
'sphinx-build' is not recognized as an internal or external command,
operable program or batch file.
The reason why the above error is emitted and not the echo.The 'sphinx-build' command was not found. Make sure you have Sphinx[...] message is because if "%1" == "" goto help is called before checking if the app is installed.
This error is at line 13, in file sphinx/sphinx/templates/quickstart/make.bat.new_t.
Line 13 should be moved to after the app check, if errorlevel 9009 ([...]).
How to Reproduce
As an end user, I receive a folder with sphinx generated files, e.g. make.bat, conf.py, Makefile, and attempt to run make by calling make.bat
Expected behavior
