[Bug]: Invalid Package.swift manifest of mapbox-navigation-native-ios in latest release

Nobody has claimed this yet.

### Mapbox Navigation SDK version

3.12.1

### Steps to reproduce

1. Clone `git clone https://github.com/mapbox/mapbox-navigation-native-ios`
2. Fetch git tags
3. Checkout `git checkout v324.15.2`
4. Execute `swift package describe`

**NOTE:** This is fixed on main branch but requires a new release of both navigation-ios and navigation-native-ios packages.

## Background

We are using [bazel](https://bazel.build) as our build system and [rules_swift_package_manager](https://github.com/cgrindel/rules_swift_package_manager) to pull in Swift packages. Problem is that [rules_swift_package_manager](https://github.com/cgrindel/rules_swift_package_manager) relies on `swift package describe` command to construct the BUILD files for bazel which in this case does not work.

### Expected behavior

The Swift Package Manager should have printed out the JSON description of the package.

### Actual behavior

```
error: Source files for target MapboxNavigationNativeTests should be located under 'Tests/MapboxNavigationNativeTests', or a custom sources path can be set with the 'path' property in Package.swift
```

### Is this a one-time issue or a repeatable issue?

repeatable

Start with Package.swift and reproduce the failure using `swift package describe` at tag v324.15.2, then compare the tagged package with the fix already present on main. Done means releasing updated navigation-ios and navigation-native-ios packages so the Swift Package Manager can emit the package description.
