docs: use as_list=False or all=True in Getting started

JohnVillalovos · JohnVillalovos · commit 094f434a17a5 · 2022-02-06T10:54:29.000-08:00
In the "Getting started with the API" section of the documentation,
use either `as_list=False` or `all=True` in the example usages of the
`list()` method.

Also add a warning about the fact that `list()` by default does not
return all items.
