Switch Yarn installation to Corepack in Dockerfiles (#846)

Replaces manual Yarn APT repository setup and installation with Corepack for Yarn management in runtimes 8.2, 8.3, 8.4, and 8.5 Dockerfiles. This simplifies the installation process and aligns with modern Node.js package management practices.
