[warning]: Do not update to 1.87+

We cannot update to 1.87+ because of
SpaiR@8a8cd22
changing Jni::InitCallbacks
https://github.com/SpaiR/imgui-java/blame/2a605f0d8500f27e13fa1d2b4cf8cadd822789f4/imgui-binding/src/main/native/jni_callbacks.cpp#L51
into something Axiom doesn't expect

We cannot update to 1.90+ without patching ImGuiFileDialog because of
ocornut/imgui@a1b8457
being a breaking change for it as seen in
https://github.com/aiekick/ImGuiFileDialog/blob/4d42dfba125cbd4780a90fbc5f75e7dfbae64060/ImGuiFileDialog.cpp#L76

We would also need to revert the disabled exts ImGuiFileDialog and
ImGuiColorTextEditor
