Subject: [PATCH] Restore import path with uppercase characters

I wasn't able to reproduce the issue described in #5492 and #5505, so
this change restores the import path with the uppercase characters
and the `ko://` prefix in the custom build example.

I had to tweak some values to get the integration tests to run,
because I don't have access to the `k8s-skaffold` project. Let's see
if the build passes.

Additional minor changes:

- Bump the ko version in the custom build example.

- Add the full path to the ko binary in the custom build script, in case
  `$GOPATH/bin` is not on the `PATH`.

Once we move to Go 1.16 for our builds, we can use the `go install`
command to install ko in the custom build shell script.
