Disable the Node platform check for Windows 7 compatibility

Node no longer officially supports Windows 7, and exits hard
in 14+ if it's used. In reality though, all functionality we
care about works - the main issue that blocks this is around
REPL behaviour. For now we just disable these checks entirely
so that the server still runs.
