Fixed build readme on Windows fails if using Git Bash (Mintty)

Git on Windows comes with Git Bash which uses Mintty.

In Git Bash the command to update the README.rst `php php-cs-fixer readme > README.rst` fails with error:

```
$ php php-cs-fixer readme > README.rst
stdout is not a tty
```

This modest contribution fixes it in Git Bash but also works in the regular command line.
