Provide binaries for oc on arm64 runners

[meibensteiner]

Is your feature request related to a problem? Please describe.

My self-hosted runner on ARM hardware is unable to use oc, the openshift client. I see in the Actions logs that the architecture is correctly read as arm64, but oc is still downloading x86, while helm is being downloaded correctly.

Describe the solution you'd like

Please download the correct binaries on arm64.

Describe alternatives you've considered

None. It would be possible to download the binaries manually, but I would rather use the plugin, if possible
