⬆️ update mqt-workflows to v1.3 (moving tag)

[burgholzer]

Description

This PR updates the MQT workflows to v1.3, which is the first version to offer moving minor tags that should reduce the update frequency.
Furthermore, the updated workflows combine the emulated wheel jobs to reduce overall build time and reduce the number of parallel jobs.
