Set --no-workspaces with npm version

[wilbert-abreu]

I need to run "--no-workspaces" or something equivalent to fix this issue npm/cli#4605, anyone know how would I can pass that to the npm version command? https://github.com/semantic-release/npm/blob/master/lib/prepare.js#LL16C42-L16C47

as mentioned in several other threads, such as #634 (comment), this can be accomplished through standard npm configuration approaches. please attempt to set this flag in your .npmrc or publishConfig in package.json
