Add platform-specific setup of the development environment

This section

https://github.com/crc-org/engineering-docs/blob/main/content/Developing.md#setting-up-the-development-environment

does not actually contain information about what is needed to set up the development environment;

• packages?
• installer
• suggested base
• info about cross compile?

As mentioned in https://crc.dev/engineering-docs/Developing.html#prerequisites it states go, make, and git are needed. However, on Windows this will not result in a working situation that easily. Probably best to describe usage with the gotoolset image, as also set-up with the devcontainer. For this podman is needed... but would have a reliable cross-platform compilation.

@anjannath and @rohanKanojia WDYT?

In my opinion, we should have separate Operating System specific instructions for any additional platform-specific requirement. If you want I can give it a try to check development setup requirements on windows and Linux.

I'm not sure about devcontainer , I have never used it.
