Kotlin DSL Missing OAuth 2.0 Protected Resource Metadata (RFC-9728)

[MarkRx]

Support for RFC-9728 was added with #17244 in spring security 7.0. The kotlin DSL needs to be updated to support the new configuration.

The DSL should support this:

http {
	oauth2ResourceServer {
		protectedResourceMetadata {
			// ...
		}
	}
}

Workaround:

// Workaround for https://github.com/spring-projects/spring-security/issues/19422
http.oauth2ResourceServer { resourceServer ->
	resourceServer.protectedResourceMetadata { metadata ->
		// ...
		metadata.protectedResourceMetadataCustomizer { builder ->
			// ...
		}
	}
}

Hi, Mark @MarkRx. I think we missed this point, so it's worth adding. PTAL: #19423.
