Container image using static-web-server

[jennydaman]

• "Production" container image uses static-web-server instead of sirv for performance, minimal image size, and feature.
  • Image size reduced from 197MB to 31.6MB.
  • ARM64 and others now supported.
• The way we build the container image is overhauled. First, we run pnpm build on-the-metal, and the dist folder is copied into a container. The work done during docker build is minimized, so multi-architectural builds using QEMU are fast.
• Using docker/metadata-action and building images for every PR to either master or staging.
• docker-entrypoint.sh was rewritten to work as a non-root user.
