Investigate netlify-cli upgrade bug

[axdanbol]

When upgrading past netlify-cli@23.9.5 npm for some unknown reason marks os/cpu specific rollup dependencies as required (missing optional: true) which breaks the the installation.

Try the following:

• Check if netlify-cli installs properly in a new project
  1. Install only netlify-cli in a new project
  2. Check rollup dependencies
• Check if there is a conflict with another package
  1. Copy package.json into a new project
  2. Upgrade netlify-cli
  3. Remove packages until rollup dependencies are marked optional

Upgrade to v23.15.1 is working without issue! :)
