`oc explain authentication.xxx.xxx` does not give good enough description for some fields as below related to external oidc config. Using this Jira to track improvement.

Any

Always

1. $ oc explain authentication.spec.oidcProviders.oidcClients
...
    componentNamespace is the namespace of the component that is supposed to
    consume this
    client configuration
...
2. $ oc explain authentication.spec.oidcProviders.issuer.audiences
...
    Must be set to exactly one value.
...
3. $ oc explain authentication.spec.oidcProviders.issuer
    issuer describes atributes ...

1 "consume this" and "client configuration" display in two lines.
2 "Must be set to exactly one value" is confusing. We can set multiple values as audiences.
3. "atributes" is a typo

1. Display in one line
2. Remove "Must be set to exactly one value"
3. Correct the typo
