Update khepri_mnesia_migration from 0.7.1 to 0.7.2

Release notes:

In particular, it makes sure that the Erlang node with the lowest Khepri
machine version is use as the cluster seed node. Otherwise these nodes
would not be able to apply commands from newer Khepri machines. See
rabbitmq/khepri_mnesia_migration#30.
