Sub generators tiles in Template Wizard.
If you want to show tile for sub generator you should add the following configuration in the package.json in the main generator:
"additional_generators": [ { "namespace": "@sap/adaptation-project:adaptation-project", "displayName": "Sub Generator Tile", "description": "Sub generator description", "homePage": "https://home.page", "image": "image.png" } ]

1. namespace value should be the namespace of the sub generator.
2. displayName is used for the name in the tile.
3. description is used for the description in the tile.
4. homePage is used for the home page of the generator.
5. image is used for the icon in tile of the sub generator
