George Kalpakas 93590895b5 build(docs-infra): update docs examples to Angular v12.1.3 (#42949)
This commit updates the docs examples to Angular v12.1.3. In addition to
updating the dependencies versions, it also updates the projects'
structure and configs to more closely match what a new v12 CLI app would
look like. See, also, the [diff][1] between a basic v11.2.11 CLI app and
a v12.1.3 one.
