fix(ci): copy .npmrc before pnpm install in all Dockerfiles

The .npmrc file contains supportedArchitectures settings to force pnpm
to install glibc x64 binaries for native modules like matrix-sdk-crypto-nodejs.

Without copying this file into the Docker image, pnpm defaults to the
platform's native behavior which may skip or install incorrect binaries.
