Use official nodejs base image, slim down image

- Playwright 1.35 supports debian 11 (bullseye), for debian 12 (bookworm) support, playwright needs to be updated
- Ensure all apt & yarn caches are cleaned in the same step they are used (slims down image)
- Image uses a lot less steps now, and slimmed down form ~4GB to 2.5GB
