Small improvements to advanced-tooling-windows

[hohwille]

Task summary

This story is about improving https://github.com/devonfw/IDEasy/blob/main/documentation/advanced-tooling-windows.adoc
Suggestions:

• Replace Windows 10 with Windows
• For perfect integration, you should (re-)install git after Windows-Terminal ... + screenshot. Question: Haven't we automated that already in our setup of IDEasy? I requested this in Improve Windows terminal integration on installation #1221 and IMHO this has been implemented. We should note this here that IDEasy automatically integrates Git-Bash into Windows-Terminal and makes it your default shell in the Terminal.
• if you find any typos fix them.
• if you know a cool general purpose windows tool that you think is missing here and most developers should be aware of simply add it here.
