[docker] yarn-berry workspace 를 찾지 못하는 오류

패키지매니저를 yarn-berry 로 쓰고 dockerfile 을 아래와 같이 작성했는데

yarn install 을 하면서

Error: nodeMediaServer@workspace:^: Workspace not found (nodeMediaServer@workspace:^)

라는 오류가 발생했다.

이유는 COPY 와 yarn install 의 순서 때문이었다.

COPY . . 를 해야 yarn install 을 하면서 워크스페이스를 찾을텐데, copy 전에 yarn install 을 먼저 해서 워크스페이스를 찾을 수 없었던 것이다.
