Big changes:

• Cymbal Branding: The UI and list of products now fit the branding of "Cymbal Shops", a fictitious company created by Google to be used in demo apps. A "CYMBAL_BRANDING" environment variable allows developers to use the "Cymbal Shops" logo and wording.

Small changes:

• GKE Autopilot instructions added to README.md.
• Typo fixed.
• Various dependency upgrades by dependabot (e.g., 590).
