--certificate or --cert?

[znewman01]

Let's sign something:

$ cosign sign-blob /dev/null --output-cert /tmp/null.crt
Error: unknown flag: --output-cert
main.go:52: error during command execution: unknown flag: --output-cert

Okay, must be "certificate":

$ cosign sign-blob /dev/null --output-certificate /tmp/null.crt
[...]

That worked! Now verify:

$ cosign verify-blob /dev/null --certificate /tmp/null.crt
Error: unknown flag: --certificate
main.go:52: error during command execution: unknown flag: --certificate

Wat.

$ cosign verify-blob /dev/null --cert /tmp/null.crt                                                                                
[...]

Oh okay ☹️

We should probably make --*-certificate the canonical flag name, and do what GNU CLIs do and accept unambiguous prefixes (if that's too big of a move in general, maybe just add aliases for these flags explicitly).
