Can't download 0.15.1 on Windows

Fails with a 404: ``` PS X:\Gloobie\gloobie> zigup 0.15.0 install directory 'X:\bin\zig' mkdir "X:\bin\zig" rd /s /q "X:\bin\zig\0.15.0.installing" mkdir "X:\bin\zig\0.15.0.installing" downloading 'https://ziglang.org/download/0.15.0/zig-windows-x86_64-0.15.0.zip' to 'X:\bin\zig\0.15.0.installing\zig-windows-x86_64-0.15.0.zip' error: download 'https://ziglang.org/download/0.15.0/zig-windows-x86_64-0.15.0.zip' failed: HTTP server replied with unsuccessful response '404 Not Found' rd /s /q "X:\bin\zig\0.15.0.installing ``` It looks like the triple target was changed, zigup tries to fetch: https://ziglang.org/download/0.15.0/zig-windows-x86_64-0.15.0.zip when the real URL is: https://ziglang.org/download/0.15.1/zig-x86_64-windows-0.15.1.zip
