Fix cortex get pretty output for async apis

[jackmpcollins]

This should fix the following error seen when running cortex get for a cluster with more async APIs than realtime.

panic: runtime error: index out of range [1] with length 1 [recovered]

checklist:

• run make test and make lint
• test manually (i.e. build/push all images, restart operator, and re-deploy APIs)
• update examples
• update docs and add any new files to summary.md (view in gitbook after merging)
• cherry-pick into release branches if applicable
• alert the dev team if the dev environment changed

Would it be possible to include this in a 0.42.1 version of the CLI which I can use against my 0.42.0 Cortex cluster?

Thanks for the fix!

We are planning on releasing v0.42.1 soon, but we do have a strict version check for the cli <> operator API (since we don't guarantee backwards compatibility yet). I do think it would make sense to relax the validation to just check that the major/minor versions match. In the meantime, the easiest thing to do would be to cherry-pick the fix on top of the v0.42.0 tag, and then build the CLI. It should be straightforward for you to do in the future if you need to, but for this fix here is the linux cli and here is the darwin cli.

Awesome, thank you!
