Thank you!

The patch (correctly) distinguishes between:

- MathJax 2 that we deprecated,
- MathJax 3 that we now use by default, and
- MathJax 4 that we support but do *not* use by default.

Most notably, MathJax 4 *re*-adds the support for (1) custom fonts and
(2) line breaks.  From the manual:

> Further, if you need to use a non-default ~font~ or ~linebreaks~ (now
> +~overflow~), then the ~path~ must point to MathJax 4 or later.

(The docstring also explicitly documents the two options as requiring
MathJax 4+.)

Even though MathJax 4 have yet to see a stable release, the patch works
with it, and the tests exercise every MathJax 4+ option as well.

Rationale:

(1) we can keep all the customization options from before,

(2) the more advanced users can use MathJax 4+ if they wish, and

(3) Org will need zero-to-none updates when 4 comes out [*].

[*]: In the expected case, we just updating the `path'.
