    extensions: fix meson build after MR !653.
    
    (1) On recent meson versions, it fixes this error:
    
    > extensions/goat-exercises/meson.build:108:0: ERROR: i18n.merge_file keyword argument 'output' was of 
type array[str] but should have been str
    
    As docs explains, 'output' only accepts one item in i18n.merge_file().
    
    This bug also happens on older meson (but there the reported error is a
    lot less useful as it doesn't mention local meson build code).
    
    (2) `setup.isl.xml` is a temporary intermediary file used to create the
        Windows installer. It must not be installed.
    
    (3) `gimp30-windows-installer.mo` itself is only used to create
        `setup.isl.xml`. It must not be installed as well.
    
    (4) gimp-tips.(its|loc) files (same for gimp-tags ones) should not be
        installed. They are only temporary data.
    
    (5) Fix environment variable: s/GETTEXT_DATA_DIRS/GETTEXTDATADIRS/
    
    Fixes:
    
    > /usr/bin/msgfmt: cannot locate ITS rules for ../../../data/tips/gimp-tips.xml.in
