Implement generate_assets_ouput for Application Import

[TamimiGitHub]

Current Behaviour

The current behaviour of the importer that assets are generated in the output directly for Event APIs only. Even when the Application mode is set to true (CLI_IMPORT_CREATE_API_APPLICATION=true) the output directory tmp/output/{domain_name}/{application_name} contains asyncapi spec file for EventAPIs

Proposal

1. Implement cliApplicationVersionImporterGenerateAssetsReturn in CliApplicationImporter.ts that uses getAsyncApiForApplicationVersion
2. Generate asset output for the respected import asset mode. For example, generate Application assets for CLI_IMPORT_CREATE_API_APPLICATION=true otherwise generate generate assets for event API import

End Goal

Recommit the asyncapi spec for the newly importer Application/Event back to the original repo to make sure repo and EP are in sync.
