Enable sanity-bot in all qt/ repos

For each qt/ repo to have the new cherry-pick workflow enabled, set the git config option "with-pickbot=true"

The following bash command can be used to iterate all qt*.git repos and set with-pickbot.

find . -maxdepth 1 -type d | for i in $(grep -P "^\./qt.+"); do (cd $i && git config sanity.with-pickbot true); done;
