Make :version consistent over search and dep add commands

[dmg46664]

The following outputs numbers

neil dep search libpython-clj                                                                             
:lib techascent/tech.jna :version 4.06 :description "Bindings to JNA.  Used with libpython-clj among others."
:lib clj-python/libpython-clj :version 2.024 :description nil
:lib cnuernber/libpython-clj :version 1.36 :description "libpython bindings to the techascent ecosystem"
:lib libpython-clj/libpython-clj :version 1.6-SNAPSHOT :description "libpython bindings to the techascent ecosystem"

However using the command expects strings or it will insert an EDN number which won't work ❗

neil dep add :lib clj-python/libpython-clj :version 2.024

So make the latter accept numbers and/or the former output strings.

An attempt in the commit above, but it's failing one test. I'd have to check later this week what's wrong.
