Remove playwright to use @playwright/test

With the playwright v1.34.0 release a breaking change was introduced where running `npx playwright test` won't work when both `playwright` and `@playwright/test` are installed.

See https://github.com/microsoft/playwright/releases/tag/v1.34.0

The image is also pinned to `:v1.34.0` to resolve the correct SHA digest, see:
