download of artifact fails for bids-validator

[yarikoptic]

I blindly assumed that

• Sanitize ~ in pathname (we do not use/rely on ~ ATM) #214

would address this but apparently not. Running 0.7.1 manually on smaug on bids-validator we get the same error

edit: per discovery in bids-standard/bids-validator#248 it is a .tar.gz file!
