iTerm port

[fcaldera]

For your consideration:
https://github.com/fcaldera/github-primer-iterm2

[cdalvaro]

I've made this port: cdalvaro/github-theme-iterm by exporting terminal colors from VSCode with command: Developer: Generate Color Theme From Current Settings.

The result is slightly different to fcaldera/github-primer-iterm2, but I think is more accurate to github-vscode-theme when you compare the VSCode terminal colors with cdalvaro/github-theme-iterm

You can download the theme for macOS Terminal app too.
