chore(examples): updates auth example to latest (#10090)

The auth example was still on `v3.0.0-beta.24`, was missing its users
collection config, and was not yet using the component paths pattern
established here: #7246. This updates to latest and fixes these issues.
This example can still use further improvements and housekeeping which
will come in future PRs.
