wwan: T3620: reorder mirgation scripts for 1.3 backport

As the new WWAN interface style is backported to VyOS 1.3 we also need to shift
the order of the interface migration scripts. so the same order from VyOS 1.4
also applies to VyOS 1.3.

In short, 21-to-22 is renamed to 18-to-19 and all other migrators are shifted
up one version.
