Documentation v4 example typo Customization --> Theme -> Typography

[marcel-k]

Took me a couple of hours before I found out why my code did not work but the v4 docs for theming typography contains a sneaky typo 👊

The example code overrides should be @font-face, not @font-family:

const theme = createMuiTheme({
  /* ... */
  overrides: {
    MuiCssBaseline: {
      '@global': {
         // '@font-family': [raleway],
        '@font-face': [raleway],
      },
    },
  },
});

@marcel-k Would you like to submit a PR? You should be able to edit it directly in GitHub, since it's a one-line change. ("Edit this page" button should link you to the right file...)
