This commit disables the Selenium Promise Manager when running e2e tests
for docs examples in order to more closely align them with new apps
created with CLI v11. This change requires that any async operations in
tests are handled explicitly (e.g. using `async/await` or
`Promise#then()`).

This commit updates the docs examples to Angular v10.1.3. In addition to
updating the dependencies versions, it also updates the project's
structure and config to more closely match what a new v10 CLI app would
look like. See, also, the [diff][1] between a basic v9.1.4 CLI app and a
v10.1.3 one.
