chore(ci): configure slt shutdown timeout to 10s

What's changed and what's your intention?

In some CI runs we find that connections cannot be shutdown in the grace period of 30s for docker stop. As a result, there's no chance for the diagnose step (#19787) to be run.

risingwave/ci/scripts/common.sh

Lines 25 to 37 in aeac64b

	function dump_diagnose_info() {
	ret=$?
	if [ $ret -eq 0 ]; then
	exit 0
	fi
	echo "^^^ +++"
	echo "--- Failed to run command! Dumping diagnose info..."
	if [ -f .risingwave/config/risedev-env ]; then
	./risedev diagnose || true
	fi
	}
	trap dump_diagnose_info EXIT

This PR configures shutdown timeout to 10s to leave some time, by bump sqllogictest to 0.28.3 to include risinglightdb/sqllogictest-rs#265.

Also fi x #22095 for CI image.
