Role template: Switching from Config to YAML editor breaks

[cnotv]

Describe the bug

When switching editor between Config and YAML for the Role Template, it breaks. The issue may be related to https://github.com/rancher/dashboard/issues/12052, although the UI does not break in that case.

To Reproduce

• Navigate to User & Authentication > Role Templates (/c/_/auth/roles#GLOBAL)
• Edit Config for an existing user role, e.g. Administrator
• Switch view to YAML

Result

Nothing happens, error in console:

entry-helpers.js:40 Error: Cannot find resourceFields for Schema management.cattle.io.templateversion (schemaDefinitions have not been fetched) 
    at get resourceFields (steve-schema.ts:103:1)

Expected Result It switches the view, just as it does for all the other resources.

Additional context

Cluster editor, Workload editor and probably all the other work as expected.

@richard-cox does this look like part of your schema diet changes? Was this one of the schemas that was removed?

[richard-cox]

It means the resource's schema model's resourceFields was accessed without the call to /schemaDefinition to populate it. There's plumbing in generic components that handle this though, so if it's a vue3 regression there's probably a hook somewhere that's not being called
