Elias Toivanen e61176d650 Bugfix: Check NodeJS version successfully even for old runtimes (Fixes #20769) (#20779)
Summary:
Fixes #20769

Release notes
--------------
[CLI] [BUGFIX] [local-cli/server/checkNodeVersion.js] - Disable auto-formatting in `local-cli/server/checkNodeVersion.js` since it introduces ES6 and ES7 syntax (trailing comma in argument list) which in turn makes ES5 engines crash with a `SyntaxError`.
