zsh completion fails

[cwrau]

What happened:
I tried for the commands which fails

What you expected to happen:
No failing but instead have completion provided

How to reproduce it (as minimally and precisely as possible):

• /usr/bin/grype completion zsh > /usr/share/zsh/site-functions/_grype
• reload zsh exec zsh
• grype <tab>
• see nothing happens

Anything else we need to know?:
