Add Windows and PowerShell commands for creating project directories and files

[MohamadSalman11]

Description

In the Bundler guide section, there were steps to create the necessary folders and files for macOS and Linux. It is also good to include commands for Windows users, as those using Windows can copy the commands and it will now work

Motivation & Context

To make it easier for Windows users to follow along and ensure consistency across all platforms

Thanks for the suggestion! I see the value in making the guide more inclusive for Windows users. That said, adding these extra steps might complicate things, as some Windows users might already find the general commands work fine (especially those using Git Bash or WSL). I'd love to hear more feedback from other Windows users like @louismaximepiton or @XhmikosR to see if this would be helpful to a broader audience.

I agree, the current instructions are enough since the people that use the native Windows CMD shouldn't be a lot.
