Zephyr SDK compatibility level 0.16 is now an LTS intended for Zephyr v3.7 LTS. Thus, limit the upper Zephyr SDK lookup to <0.17, so that developers working with Zephyr v3.7 LTS and latest Zephyr main can install both Zephyr SDK 0.16.x along side Zephyr SDK >=0.17 and have the Zephyr SDK 0.16.x series being used for v3.7 LTS development.
