How to reproduce:

2. Import the 'Visual Scripting' package
3. In the Project Window, create a new Script Graph (Create->Visual Scripting->Script Graph)
4. Open the created Asset (Double-click)
5. In the Build Settings, switch to the WebGL Platform
6. Make a build
7. Wait for the process to finish
8. Inspect the Console Window

Expected result: The Player is built successfully
Actual result: Build fails as multiple "The type or namespace name 'ReadOnlySpan<>' does not exist in the namespace 'System'" errors are thrown
