Issue:
Enable no-bin-links for community.general.npm
### Summary

I'm working on getting a vagrant development environment setup and am running into an issue where npm is having trouble installing on a synced folder. A solution would be to enable a flag to add the --no-bin-links setting to disable symlinking executables but there's no way to set this currently.

### Issue Type

Feature Idea

### Component Name

community.general.npm

### Additional Information

<!--- Paste example playbooks or commands between quotes below -->
```yaml (paste below)
- name: NPM install for Login Service
  community.general.npm:
    path: "{{ project_root }}"
    links: no
  become_user: vagrant
```
