Update `build.zig.zon`, and then if the headers changed, regenerate them into `src/cached` with [dear_bindings](https://github.com/dearimgui/dear_bindings).

Building `cimgui.h` is explained in their README, here'd how to build a backend. You can also see the command format in their `bindings.bat` file. Here's how to build `cimgui.h`:
```sh
python3 $DEAR_BINDINGS_PATH/dear_bindings.py -o src/cached/cimgui $DEAR_IMGUI_PATH/imgui.h
```
Here's how to build a backend, using Vulkan as an example:
```sh ```sh
python3 dear_bindings.py --backend --imconfig-path ~/Documents/imgui/imconfig.h -o cimgui_internal ~/Documents/imgui/imgui_internal.h python3 $DEAR_BINDINGS_PATH/dear_bindings.py --backend --imconfig-path $DEAR_IMGUI_PATH/imconfig.h -o src/cached/cimgui_impl_vulkan $DEAR_IMGUI_PATH/backends/imgui_impl_vulkan.h
``` ```
If `generator.zig` fails, you may need to add missing values to the enumeration. `std.json` does not provide helpful errors at the time of writing, the easiest way to debug this is to comment out the actual generation code, and all fields in `Header`, adding them back until you figure out which are causing the issue.
