fix(core): fix having multiple versions of nx/devkit

[FrozenPandaz]

Current Behavior

@nrwl/devkit brings in nx as a dependency which causes an issue where nx's postinstall is run multiple times. This causes some CI machines to run out of memory. Also, installing packages during generators, is able to dedupe installs during the same installation of devkit, but it is not able to dedupe across multiple versions of devkit.

Expected Behavior

@nrwl/devkit has a peer dependency on nx. The range for this dependency goes up a major version as we should keep nx compatible with devkit. This will fix having multiple versions of nx installed. This fixes some CI machines to run out of memory. Also, installing packages during generators, is able to dedupe installs across different installations of devkit.
