-f and -l imcompatibilities

[bmc]

Requiring -l is silly (and, in fact, ignored, as expected) in this use case:

databricks workspace import -f DBC -l SCALA /path/to/some.dbc

The entire DBC is loaded, without respect to the language(s) of the contained notebooks (which, of course, is what I want to happen). But I'm still required to specified -l <language>.
