Generate documentation for default builders

AIO has a page on `angular.json` workspace configuration which lists [default builders](https://angular.io/guide/workspace-config#default-architect-builders-and-targets). Unfortunately these builders link directly to the [JSON schema](https://github.com/angular/angular-cli/blob/main/packages/angular_devkit/build_angular/src/builders/browser/schema.json), which is not very intuitive.

We should process these schema files and generate a page for each builder linked from the workspace configuration. This would make it much easier to understand `@angular-devkit/build-angular` and related builders' options.

从 AIO 工作区配置页面和链接的默认 builder schema packages/angular_devkit/build_angular/src/builders/browser/schema.json 开始。跟踪如何将 schema 文件处理为文档页面，并从默认 builder 列表链接到这些页面。完成的标准是每个相关 builder 都有一个易于理解的生成页面，并且工作区配置链接到这些页面，而不是直接链接到 JSON schema。
