Examples for testing are designed specifically to run in StackBlitz and
are not regular cli projects (e.g. their `main.ts` files may load and run
tests instead of bootstrapping an app). They are not intended to be
downloaded and built/run locally using the cli.
In order to avoid confusing users, this commit removes the download links
from the guide. If desired, the projects can still be exported locally
via StackBlitz's UI.
Related to #31020 and #31937.

This commit removes all occurrences of the `format` attribute on code
examples.
