Steps to reproduce the issue
Upgrade kibana plugin from version 1.38 to 1.60
Expected result:
Everything works 
Actual Result:
Kibana failed to start. Log messages:
[09:17:58:938] [info][plugins][ReadonlyREST][ConfigurationCompliance] ConfigurationCompliance: isFree=false, isEnterprise=false
[09:17:58:939] [error][plugins][ReadonlyREST][ConfigurationCompliance] ❌ "Login page customizations" is only available for Enterprise subscribers.
[09:17:58:939] [error][plugins][ReadonlyREST][ConfigurationCompliance] FATAL: Current Activation Key is for a "PRO" license. Your kibana.yml enables features that are not available at this subscription level. You can upgrade to an Enterprise license at https://readonlyrest.com
In kibana.yaml I use readonlyrest_kbn.login_custom_logo and readonlyrest_kbn.login_html_head_inject witch worked fine with version 1.38 of kibana plugin. And, according to docs should work with latest version.
Issue is connected only to this two settings - after commenting them out kibana starts without problems.
