recipetool: create: npm: Add support to handle peer dependencies

NPM changed its manner to handle peer dependencies over its versions.
Before NPM 3: NPM installs automatically peer dependencies
between NPM 3 and 7: NPM shows a warning about peer dependencies
After NPM 3: NPM reworked its manner how to handle peer dependencies

The shrinkwrap doesn't have the parameters of the peer dependencies, so we cannot
fetch them. in the same time peer dependencies are not direct dependencies, they should
be installed as run time dependencies.
