* Add tests

* Fix compiling keymaps directly from keymap directory

* Schema should not require version for now.

fix helix/rev2:edvorakjp build error (#16433)

'helix/rev2/keymaps/edvorakjp' was no longer buildable due to changes made by #14864.
The reason is that the prototype of `oled_task_user()` was changed in keymaps/edvorakjp/oled.c, but keymaps/edvorakjp/oled.h was not changed.
Therefore, I modified the prototype in keymaps/edvorakjp/oled.h.
