Underscores no longer allowed in devspace commands in v6

What happened?
Upgraded to v6. Underscores no longer allowed in devspace commands. Switching it to dashes worked.

What did you expect to happen instead?
Underscores allowed.

How can we reproduce the bug? (as minimally and precisely as possible)
