Unifies naming for isArray in Schema class properties

Created by: spacether

We are using multiple properties that mean this schema is type array. The properties are:

• isListContainer
• isArrayModel

This PR updates our java classes that implement Schema to be consistent in out naming and getters and setters for this property. These classes have been updated:

• CodegenProperty
• CodegenModel
• CodegenParameter
• CodegenResponse

This PR:

• changes isListContainer + isArrayModel to isArray
• some locations were missed when changing to isMap, fixes those locations too
• is a feature break out for https://github.com/OpenAPITools/openapi-generator/issues/7651

You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
