Prefer text-input-v2 over text-input-v3 for now

Browse Source 
Qt's current text-input-v3 is converted from text-input-v4, but it's
current state is poor and does not support the same feature like v2.
KWin is the only major party that implements text-input-v2 and many
feature e.g. Plasma-mobile would require v2 feature to provide the
complete support. Until v3 is as good as v2, prefer v2 over v3 should
provide a smoother experience on KWin (for both 5/6) out of box and
won't affect other compositor.

Pick-to: 6.7
