chore(devcontainer): fix dockerfile broken yarn repo in base image (#2065)

This PR fixes the broken Yarn APT repository present in the mcr.microsoft.com/devcontainers/java:1-21-bullseye base image by removing /etc/apt/sources.list.d/yarn.list before running apt-get update, and migrates the devcontainer config from a bare image reference to a Dockerfile build. It also bumps the Android platform and build-tools from 35 → 36, removes the redundant Java devcontainer feature, and delegates Node.js installation to the ghcr.io/devcontainers/features/node:1 feature (commenting out the previous fnm-based install)
