CI: Use fontforge March 2022 to create patched fonts

[why]
Fontforge 2020 March or 20th Anniversary have problems to generate fonts
with a lot of table entries. This is for example the massive entries for
ligatures in Iosevka. We can not generate valid font files with that
fontforge versions. We can not even detect (from Python side) if
fontforge had problems.

[how]
We fixed fontforge itself upstream with
  https://github.com/fontforge/fontforge/pull/4883

That fix became available first with Fontforge March 2022 Release.

We could use the AppImage or build from scratch, because no package is
available on Ubuntu 20.04 or 22.04.
