Yes, indeed I adapted it from LICENSES/dual/CC-BY-4.0.

Another alternative is to put license notice on CSS code that includes
the font. In this case, in Documentation/sphinx-static/fonts.css, the top
of the file should've been written as:

```
/* SPDX-License-Identifier: GPL-2.0 */
/* IBM Plex Sans, IBM Plex Mono, and Newsreader is licensed under the SIL Open
 * Font License, version 1.1. See OFL.txt in the same directory as this file
 * for details. */
<actual stylesheet>
...
```

Is above acceptable?
