dev env setup handle golang cert issues on macOS

[KevinMGranger]

There's an outstanding issue with go's x509 library that broke invalid certificate handling on macOS. If you're using some local cluster with self-signed certs, ignoring their validity won't work.

If you're using OpenShift Local / CRC, then their bundled oc version actually works around this! But I always forget about that when remaking my dev environment 😅.

A reminder would be nice.

Alternatively, since the workaround is to use the 4.10 version of oc, maybe the script should just use that version on macOS for now?

@KevinMGranger #709 is merged, however we should track the issue with the oc on Mac somewhere so it will get updated when it's fixed.
