Document how to run tools

[pascalberger]

We should document different ways to run external tools:

• Using built-in aliases from Cake.Common
• Using alias provided by an addin
• Using Command aliases introduced with 2.3.0: https://cakebuild.net/blog/2022/10/cake-v2.3.0-released#command-aliases
• Using StartProcess aliases
