a2a library dependency in Dockerfile

[xbill9]

The Dockerfiles in the social, platform_mcp_client , and planner build directories are inconsistent.

this line was removed from platform_mcp_client Dockerfile:

COPY ./a2a_common-0.1.0-py3-none-any.whl /app/a2a_common-0.1.0-py3-none-any.whl

This agent will not build independently as the build for the agent fails because of the
missing library inside the docker container.

The other 2 agents still build because the dependency is copied into the build.

If the line is removed from the other Dockerfiles the independent build will fail for all 3.

I am +1 to that issue - tested it yesterday and found the platform_mcp_client build was not working because of that missing line.

I'm in the middle of updating the workshop. I'll let you know when the update is done.
