winGRASS: change form BU Execute to "GenericRead + GenericExecute"

[dnewcomb]

This PR changes Line 761 of of the nsis installer template in the mswindows directory, GRASS-installer.nsi.tmpl from using "BU" "Execute" to using the language - independent ""(s-1-5-32-545)" "GenericRead + GenericExecute"
Should fix issue identified in #1965 . Fix based off information at https://peter.bloomfield.online/nsis-access-control-problem-with-built-in-users-group/ , where the BU permissions option does not work on installations of a different language than the language the NSIS installer was created on Windows version 8 and above computers.

@neteler will there another release in the 7.8.x line? If yes, then this needs to be backported

@dnewcomb please use a short meaningful PR title, as it is used for the ChangeLog (feel free to modify my title suggestion above). Thanks.

@neteler will there another release in the 7.8.x line? If yes, then this needs to be backported

It also needs to be forward-ported as this PR is currently against relbranch80.

New title is fine.

I merge now this PR via the gh website.

as I don't have my dev/build environment at hand here at the moment, @neteler may I ask you to backport and forward-port this PR? thanks.
