Make boat-maven-plugin goal doc to run in Java 17.

[fredysierra]

When running boat-maven-plugin goal doc. With parameters:

<engine>handlebars</engine>
<generatorName>boat-marina</generatorName>

New version of the plugin requires Java 17 and this goal does not work in Java 17

Additionally, model doc generated ignores Array type fields. Those are not shown in Portal Api and those produce inconsistencies in the documentation.

For that, BoatMarinaGenerator was changed with property generateAliasAsModel as true

Would it be possible to add test coverage for these goals?
