feat: enable vt processing on windows (#7158)

### Description

If we're on windows and are attempting to emit colors, help our users by
setting
[`ENABLE_VIRTUAL_TERMINAL_PROCESSING`](https://learn.microsoft.com/en-us/windows/console/setconsolemode)
which allows ANSI color escape sequences to be respected by the Windows
console. This might already be set to true by some users, but it is not
enabled by default by Windows.

### Testing Instructions

Look at the pretty colors on Windows!

(My default powershell colors are horrible and end up making the
`docs:build` prefix invisible)

Closes TURBO-2186
