Updates for all angular.io links to the new angular.dev domain. Additionally, adjustment to new resources where the equivalent does not exist on the new site (e.g. Tour of Heroes tutorial)
This commits adds an optional migration to migration existing projects to use the vite and esbuild based application builder.
The migration can be opted-in when running `ng update @angular/cli --name=use-application-builder`
The `@schematics/angular` package now contains a defined set of package `exports` including a `utility` subpath export.
A wildcard export is also temporarily defined to support transition away from existing deep-import usage.
The `@schematics/angular/utility` subpath export will contain supported utility methods used by the first-party schematics
contained within the `@schematics/angular` package and can be considered public API that will follow SemVer stability constraints.
The first group of utilities introduced in this change are used to modify the `angular.json` workspace file
within the schematics and include the `updateWorkspace` rule and `readWorkspace`/`writeWorkspace` helpers.
Code related to decoding buffers into strings and parsing content into JSON can now be removed by using the
support provided directly from the Tree instance for the executing schematic.
