Fixes#35373.
This changes the example from "run an arbitrary process" to "copy a file". This should make it a bit easier to follow, require less background knowledge to understand, and not use any platform-specific commands that won't work for Windows users.
The most glaring issue with this change is that this doc does not explictly specify how to build and run a builder. I've updated some of the files to hint at this a bit more (such as the `"implementation": "./dist/my-builder.js"`), but another pass is required to figure out the best way to compile a builder and how we want to structure this example to best communicate that.

PR #36601 introduces icons on all links if the link contains
https:// or http:// but there were some internal links left
which contained https://angular.io. Removed https://angular.io
from all these links.

Previously, the examples in the `cli-builder` guide were hard-coded.
This made it impossible to test them and verify they are correct.
This commit fixes this by converting them into a proper mini-app. In a
subsequent commit, tests will be added to verify that the source code
works as expected (and guard against regressions).
Fixes#34314
PR Close#34362
The `format` attribute is an artifact of an old version of the docs
tooling (before moving it into the angular/angular repo) and no longer
does anything. People are still copy-pasting it from existing examples.
This commit removes all occurrences of the `format` attribute on code
examples.
