⚠ Note
This action has been superseded by openshift-tools-installer, which can install oc as well as other CLIs. It has support for caching across multiple workflows, and allows inputting semantic version ranges.

[kovayur]

Switch to oc to align with other targets

[kovayur]

Add --ignore-not-found to make the command idempotent and not fail if the chart is already uninstalled.
