Update examples and tutorials (#2139)

Motivation:

We're going to tag beta.1 soon, so the examples and tutorials need to be
updated to reflect this.

Modifications:

- Regenerate example code
- Update example code to use new APIs
- Update example manifests to use the as-yet-unreleased beta.1 tag of
  each dependency

Result:

Examples are up-to-date
