New description:

 When I install QGIS LTR 3.22.4 using the package based installer
 (individual packages, not the meta-package) along with GRASS 7.8 and run
 the C:\OSGeo4W\bin\qgis-ltr-bin.exe, the GRASS processing provider is
 broken, and trying to run any GRASS processing tool gives the following
 error:

 ''This algorithm cannot be run :-(
 The specified GRASS 7 folder "C:\OSGeo4W\bin\bin" does not contain a valid
 set of GRASS 7 modules. Please, go to the Processing settings dialog, and
 check that the GRASS 7 folder is correctly configured''

 The same behaviour is not seen with the standalone QGIS installer.

 From [[https://github.com/qgis/QGIS/pull/47163|#47163]] I can see that
 this message is returned by Grass7Utils.py, and after some exploration I
 discovered that this is because the GISBASE environment variable is not
 set.

 If QGIS is launched via the batch file: C:\OSGeo4W\bin\qgis-ltr.bat, then
 GISBASE is correctly set and the GRASS processing tool function correctly.

 The OSGeo4W package based installer creates a Windows shortcut that points
 to the C:\OSGeo4W\bin\qgis-ltr-bin.exe, and therefore when this is run,
 the bug exhibits itself.

 **Steps to reproduce the issue**

 With the OSGeo4W package installer, install QGIS LTR 3.22.4 along with
 GRASS 7.8 (7.8.7-1) on MS Windows. Load QGIS via the Start Menu shortcut.
 In QGIS, open the Processing panel and double click on a tool from the
 GRASS provider.

 Check the status of the GISBASE environment variable through the QGIS
 python console by executing:

 {{{
 os.environ['GISBASE']
 }}}


 **Environment:**

 QGIS: 3.22.4
 GRASS: 7.8.7-1
 OS: Windows 10 64bit
