There is MUI_WELCOMEPAGE_TEXT but it is only useful if you want to change all of the text and not just append something.

During the show function for the page, you can change the text of any control:

outfile test.exe
requestexecutionlevel user

!include MUI2.nsh

#!define MUI_WELCOMEPAGE_TEXT "New text goes here"
!define MUI_PAGE_CUSTOMFUNCTION_SHOW MyWelcomeShowCallback
!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_LANGUAGE "English"


Function MyWelcomeShowCallback
SendMessage $mui.WelcomePage.Text ${WM_SETTEXT} 0 "STR:$(MUI_TEXT_WELCOME_INFO_TEXT)$\n$\nVersion: foo.bar"
FunctionEnd

!include MUI2.nsh

!define MUI_PAGE_CUSTOMFUNCTION_SHOW MyWelcomeShowCallback
!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_LANGUAGE "English"


Function MyWelcomeShowCallback
${NSD_CreateLabel} 120u 150u 50% 12u "Version: foo.bar"
Pop $0
SetCtlColors $0 "" "${MUI_BGCOLOR}"
