An "Unknown reflection probe mode: 1" error is thrown when baking Realtime Reflection Probes

Steps to reproduce:

1. Create and open a new URP 3D project
2. Create a Reflection Probe in the Hierarchy
3. Change its type to "Realtime" in the Inspector
4. Open Window -> Rendering -> Lighting
5. Next to "Generate Lighting" press the dropdown and select "Bake Reflection Probes"
6. Observe the Console

Actual results: An "Unknown reflection probe mode: 1 UnityEditor.GenericMenu:CatchMenu (object,string[],int)" error is thrown

Expected results: Realtime Reflection Probes are ignored and no error is thrown

Reproducible with versions: 2023.1.0a10, 6000.0.73f1, 6000.3.14f1, 6000.4.5f1, 6000.5.0b6, 6000.6.0a4

Tested on (OS): Ubuntu 24.04, Windows 11 Pro (25H2)

Notes:

• Baking Custom and Baked Reflection Probes does not throw any errors
• Same thing happens when baking all probes from the Inspector of a "Baked" type Reflection Probe
