feat(docker): reduce the size of alpine docker images (#3973)
* reduce redundant code between the two alpine Dockerfiles * reduce the docker image build times * reduce the `n8n` image size from 1.17GB to 462MB * reduce the `n8n-custom` image size from 671MB to 460MB * reduce the size of npm tree by making all typing packages devDependencies Partially resolves this ticket: N8N-3252
