updated readme

[minco3]

basic_test.cpp

• Changed "" for <> as gtest is being included as a library not a relative path
• Removed main function as Modernize CMakeLists.txt CS3A_Template#1 will link against the gtest_main target which provides its own main function

mac.md

• Clarified the install guide, now uses GitHub CLI to provide authentication rather than having to create a personal access key.

windows.md

• Complete rewrite to switch from MinGW to MSYS2/ucrt64 as it is now the recommended environment (see [msys2/mingw64] recommend using ucrt64 instead of mingw64 microsoft/vscode-cpptools#11063)
• Using MSYS2 will allow for easier install of CMake and eventually SFML
• The windows guide now also uses GitHub CLI to provide authentication

Perfect code!

Glad you like it, I'm going to make another pass and add some more pictures. Should I add a link to Visual Studio Code?

and add some more pictures. Should I add a link to Visual Studio Code?

What is the link for?

What is the link for?

just so people know where to find vscode, I don't think we have a link anywhere but maybe I'm forgetting something.
