Issue description

Current behavior:

https://akveo.github.io/nebular/docs/guides/install-based-on-starter-kit#install-based-on-starter-kit Follow the instructions exactly and install fails. npm saas is deprecated? I am new to Angular and wanted something that was partially done. Surprised that I couldn't even install the sample code following the instructions exactly using Ubuntu 20 LTS. Expected behavior:

The sample application works. It installs without error Steps to reproduce:

Go to https://akveo.github.io/nebular/docs/guides/install-based-on-starter-kit#install-based-on-starter-kit Follow the setup instructions exactly. When you get to npm i, it will fail.
