Application Builder migration docs should mention new folder structure in dist #57247

Describe the problem that you experienced

The documentation of the application builder migration for existing applications does not mention the new folder structure in the dist folder. With the browser builder, after a successful build the bundle is located in dist/<project-name>. After migrating to the application builder, it is located in dist/<project-name>/browser. Developers should be aware of that, so in case they have a custom deployment, the path is updated.
