chore: Update Hexa.NET.ImGui to the latest

[VaclavElias]

Not urgent. There is some error when upgrading to 2.2.2.

That is a strange issue, it seems to be complaining about a empty ID for a window but it seems like it should be there and is not empty...

Checking the below line, it clearly shows that it has the name of the relevant created BaseWindow.

stride-community-toolkit/src/Stride.CommunityToolkit.ImGui/ImGuiExtension.cs

Line 83 in e772e56

collapsed = !Begin(name, ref open, flags);

error:

Assertion failed: id != window->ID && "Cannot have an empty ID at the root of a window. If you need an empty label, use ## and read the FAQ about how the ID Stack works!", 
file D:\a\Hexa.NET.ImGui\Hexa.NET.ImGui\cimgui\imgui\imgui.cpp, line 11416

Not sure what I'm missing here.

Note: it has broken in version Hexa.ImGUI 2.2.0 since the ImGUI 1.91.4 release.

Interesting. We could ask the author, but it isn't urgent. Just noted here, so we don't forget.
