command-not-found missing versioned dependency on python3-commandnotfound

[Steve Langasek]

command-not-found and python3-commandnotfound should generally be updated at the same time, but cnf doesn't have a versioned dependency on the python3 package. If an older python3-commandnotfound is installed, you get:

A versioned dep on command-not-found-data is also needed, as the data file format has changed incompatibly.
