Create a proof-of-concept end-to-end (E2E) starter repository

[kniedermaier]

The E2E starter proof-of-concept should have:

1. a simple toy application (e.g. https://github.com/navapbc/template-infra/tree/main/app)
2. some simple playwright tests against the toy app

In addition, the proof-of-concept should address the technical implementation considerations found in the related 🔒 tech spec:

1. Provide scaffolding for Playwright configuration
2. Include an example test
3. Document initial configuration settings and setup requirements and an overview of how to run these tests as part of local development
4. Integrate Playwright with CI/CD as part of a Github Actions workflow

This work will help answer the last outstanding question in the "End-to-end starter" 🔒 tech spec around whether it makes sense to create a separate E2E starter template or to embed an E2E starter in existing application templates.
