Let's see if this works

/kind/bug
(it didn't, boo)

(gonna treat it as a bug because 0.5.0 has an issue whereby the files it produces, we think, have the wrong permissions)

/kind bug

Digging back through some slightly older issues I spy #370 which hasn't closed out yet and a thread on ko that I think suggests this is fixed in 0.5.1? ko-build/ko#164

I'm not sure if there's a way to test this short of merging it and seeing what fails. WDYT @afrittoli ?

Also, https://github.com/google/ko/releases shows that 0.5.0 and 0.5.1 are targeting the same commit 😅
