fix(docker): update Dockerfile to copy full source for extensions and adjust build process

Modified the Dockerfile to copy the full source of the `extension-hypermultimedia` and `extension-inline-code` packages instead of just their package.json files. Updated the build process to install dependencies and build the extensions before the production install, ensuring a cleaner setup.
