Add steps for using an alternative to Docker

[michaelsaki]

💡 Summary

Currently Docker no longer is a free to use for larger companies. See here for more details

An alternative like colima should be added to the development guide for developers looking for a free alternative.

Motivation and context

This belongs in here because currently the development guide provides steps for using Docker and no other alternative. To stay in the spirit of OSS we should provide an alternative that is free to use.

Acceptance criteria

• [ ] Mac-env-setup.md is updated to include Colima as an alternative.

As a Linux lover myself I would agree but I do try to make everyone happy 😆
