Docs: Feedback for Managing Enterprise License Keys

Hi, I have some feedback about [this page](https://github.com/hazelcast/hz-docs/edit/main/docs/modules/deploy/pages/enterprise-licenses.adoc)

In embedded mode(java code creating a enterprise member) the member reports incorrect java system license property, also does NOT pick up exported environment variable HZ_LICENSEKEY...
To set the license key, please do one of the following:
- Change member config using Java API: config.setLicenseKey("...")
- Change XML/YAML configuration property: Set hazelcast.license-key: ...
- Add system property: -Dhz.licensekey=... (for Hazelcast embedded, works only when loading config via Config.load)
- Add environment variable: HZ_LICENSEKEY=... (recommended when running container image. For Hazelcast embedded, works only when loading config via Config.load)

-Dhazelcast.enterprise.license.key=$HZ_LICENSEKEY works.
