This is a temporary workaround for having all prometheus-operaotr CRDs in a single file:
We also host a minified version of the merged CRD files which has the description fields cropped.
This causes inconvenince when dealing with CRDs with commands like kubectl explain, but is essentially an effective workaround for the
prometheus-community/helm-charts#1500 issue.
Follow these steps to get the file ready.
