Doctest builds on 3.11 have started failing:

This is because ubuntu-latest is used, and that now points to 26.04, which no longer has the lzma-dev package.

3.12+ was already pinned to ubuntu-22.04 (#125236) and upgraded to ubuntu-24.04 (#128504).

(3.14+ have also been upgraded to ubuntu-26.04 (#152717).)

So the easiest thing to do here is pin to ubuntu-24.04, like 3.12 and 3.13.

This PR also includes some other minor changes, to make it more similar to the 3.12 file, and easier to compare/maintain in the future.
