Serenity/JS docs should be more Windows-friendly

[jan-molak]

What's the problem you're trying to solve?

To improve readability, many npm install commands described at serenity-js.org rely on bash brace expansion. For example:

npm install --save-dev @serenity-js/{code,rest,console-reporter}

However, Windows does not support this syntax and attempts to execute a command like this result in an error:

How would you like to solve it?

Since commands relying on bash brace expansion are used on the website and in the readme files, we should use one command syntax that works across the OS-es, even at the cost of decreased readability (since most people will probably just copy and paste them anyway).

Are there any alternatives?

We could recommend to Windows users to use WSL instead of Windows terminals, but setting it up might not be convenient or even possible in many corporate settings.

How can we make it happen?

• work on this myself (with Serenity/JS team guidance)
• hire the Serenity/JS team to build it for me
• add it to the Serenity/JS backlog and wait for a volunteer
