Incorrect return and data type in license api

[s4mur4i]

While developing for api endpoint /manage/v1/config/license we detected 2 issues, which are not consistent with api docs
https://docs.github.com/en/enterprise-server@3.19/rest/enterprise-admin/manage-ghes?apiVersion=2022-11-28#get-the-enterprise-license-information. We opened support case, and verified with github support our findings.

1. The response is advertised as: [{...}] but actual response is {...}
2. supportKey is actual a bool return.

Example response:
curl -u api_key:xxxx https://hostname:8443/manage/v1/config/license
