Update and DRY role sets used for local development

[cadenmarchese]

Which issue this PR addresses:

Fixes no jira

What this PR does / why we need it:

• We store a local copy of our current role sets for dev cluster purposes. The real copy lives in RP-Config.
• I wanted to update what was there since it's out of date, but since the role set has been consistent across versions (so far), I converted the role set to YAML so that we can use anchoring and get rid of some of the duplication.
• We can't use a single role set for all versions since role sets are version-specific and expected to evolve with OCP.
• The RP still expects JSON role sets so render it out to JSON using yq

Test plan for issue:

• Ran the script locally to confirm it works.

Is there any documentation that needs to be updated for this PR?

No - end functionality doesn't change.

How do you know this will function as expected in production?
