Launch from dir with spaces

[Rjialceky]

Add quotes around references to %OSGEO4W_ROOT%\bin\qgis*.bat to enable launch when that path may contain spaces. For example, if %OSGEO4W_ROOT% is "%userprofile%\Program Files", required change to qgis-ltr-grass.bat line:

From:
IF "%1" == "" (start "QGIS" /B %OSGEO4W_ROOT%\bin\qgis-ltr.bat --profiles-path %DRV_LTR%\qgisconfig) ELSE (start "QGIS" /B %OSGEO4W_ROOT%\bin\qgis-ltr.bat --profiles-path %DRV_LTR%\qgisconfig --project %1)

To:
IF "%1" == "" (start "QGIS" /B "%OSGEO4W_ROOT%\bin\qgis-ltr.bat" --profiles-path %DRV_LTR%\qgisconfig) ELSE (start "QGIS" /B "%OSGEO4W_ROOT%\bin\qgis-ltr.bat" --profiles-path %DRV_LTR%\qgisconfig --project %1)
