build: update to support BETA release process

See discussion: https://github.com/orgs/AlaskaAirlines/discussions/556

Here's a brief description of the changes:

1. `.github/settings.yml`: This file is used to configure GitHub repository settings.
   The changes made here include:
   - The branch protection rules that were previously applied to the `main` branch are
     now defined under a YAML anchor `default_protection`. This allows the same
     set of rules to be reused for multiple branches.
   - The `main` and `beta` branches are now using the `default_protection` rules.

2. `.github/workflows/testPublish.yml`: This file defines a GitHub Actions workflow.
   The changes made here include:
   - The workflow is now triggered on `push` and `pull_request` events not only for
     the `main` branch but also for the `beta` branch.
   - The `release` job now runs if the event is a `push` to either the `main`
     or `beta` branch.

3. `package.json`: This file is used to manage the project's dependencies, scripts,
   version and more. The changes made here include:
   - The `release` configuration now includes the `beta` branch in addition to the
     `main` branch. The `beta` branch is marked as `prerelease`. This means that
     releases on the `beta` branch will be marked as pre-releases.
