Update installation instructions and add Windows layout files

[anthonypz]

This PR includes Windows installation files for Graphite and updated installation instructions for Windows. I've also included an angle modded version of Graphite for convenience.

Changes made:

• Improved formatting and clarity of installation steps for both MacOS and Windows
• Added an explanation of the Angle Mod variant
• Included visual keyboard layout comparisons for both standard and angle-mod versions

Testing done:

• Verified that shifted symbols and letters worked correctly
• Verified that Ctrl + Shift + <key> shortcuts worked correctly
• Verified that Ctrl + <key> shortcuts worked correctly
• Confirmed Windows installation steps

If there is anything I missed or something you would like changed, please let me know.

I would suggest including the .klc sources instead of executables. Not only this would allow people to customize the layout (AltGr behaviour, dead keys, etc.), but it would also avoid security concerns.

Great idea. I added the .klc files and wrote a description of what they are and how they can be used in the INSTALL.md file. I also left the executables for convenience in case others find the process of installing MSKLC too burdensome. When I installed MSKLC on a fresh Windows 11 PC, I had to install an older version of .NET that took almost an hour to complete.

If security is a top priority, I can go ahead and remove the binaries if needed.
