How to reproduce:
1. Create a new 3D URP Sample Project
2. Open the Console window
3. Observe the warnings in the Console window

Expected result: No warnings appear in the Console window
Actual result: 8 Warnings appear in the Console window

Reproducible in: 6000.0.0b11, 6000.0.19f1
Not reproducible in: 2021.3.43f1, 2022.3.46f1, 2023.3.0b10

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Notes:
- Warnings are specific to the 3D URP Sample project (Was not reproducible on HDRP Sample/Template projects, URP 2D/3D template projects).
- Restarting the project clears these warnings and they do not appear again. (Can achieve the same thing by also clearing everything in the Console window).
- 6000.0.19f1 seems to have one extra warning compared to 6000.0.0b11 version (warning CS0108: 'FullscreenPassBase<T>.passName' hides inherited member 'ScriptableRenderPass.passName').
