feat: dont error out on version parse if we fail, just skip dealing w/ license secret

[carlmontanari]

title! some folks are wanting to use arbitrary tags and currently this results in us returning an error from the image/tag parsing which prevents us from getting a pod deployed. this pr simply returns an empty version object rather than an error if we can't parse things. worst case folks will have no secret.

holler if this needs tweaking and ill get whatever sorted!
