Adding system UIImages to map gives `mismatched image size`

Nobody has claimed this yet.

## Environment

- Xcode version: 15.3
- iOS version: 17.4
- Devices affected: N/A
- Maps SDK Version: 11.3.0.rc1

## Observed behavior and steps to reproduce

When I try to use the following code to add system `UIImage` to a `MapboxMap` called `map`:

```swift
try map.addImage(
UIImage(systemName: "mappin")!,
id: "pin"
)
```

I get an error: `StyleError(rawValue: "mismatched image size")`.

## Expected behavior

I should be able to use this image the same way I can use images that come from my `Assets`.

## Notes / preliminary analysis

## Additional links and references

Start by reproducing the issue with the `map.addImage` call and a system `UIImage` named `mappin` on the stated Maps SDK, Xcode, and iOS versions. Trace the image-size validation reached by `addImage`; done means system images can be added without `StyleError(rawValue: "mismatched image size")`, while existing asset images continue to work.
