[DOCS] Move preconfigured Tines connector details

[lcawl]

Summary

This PR:

• Moves the preconfigured connector examples from https://www.elastic.co/guide/en/kibana/master/tines-action-type.html to https://www.elastic.co/guide/en/kibana/master/pre-configured-connectors.html since that functionality is only applicable if you are running Kibana on-prem and therefore won't be applicable to serverless projects.
• Adds the setting names to https://www.elastic.co/guide/en/kibana/master/alert-action-settings-kb.html
• Adds the same config and secrets properties to the openAPI specification
