CImGui currently broken

[heyx3]

CImGui.jll has a new version of the underlying CImGui library, but has not updated its user-facing code accordingly. This has left it in a broken state for a handful of widget types (breaking BpWorld but not much else).

We should try to help push the package through its next update, or revert B+ to the specific older version that worked until this is fixed.

For reference, the original version of the packages we used was:

• CImGuiPack_jll: 0.1.2+0
• LibCImGui: 1.82.2
• CImGui: 1.82.0

The update that caused this problem was:

• CImGuiPack_jll: 0.2.0+0
• LibCImGui: 1.89.5
• CImGui: 1.82.0

It looks like the update to CImGui.jl is very nearly done, they're just working on some CI documentation issues

Fixed by explicitly fixing the CImGui and LibCImGui versions.
