Scene 24 shaders broken

Steps to reproduce:

1. Create a new project with the Universal 3D template.
2. Right-click Hierarchy > UI > Text - TextMeshPro
3. Import TMP Essentials, as well as TMP Examples & Extras.
4. Open Assets > TextMesh Pro > Examples & Extras > Scenes > 24 - Surface Shader Example.

Actual results: Everything in the scene is purple. No errors in console.

Expected results: No issues with the scene.

Reproducible with versions: 6000.0.10f1, 2022.3.33f1, 2021.3.39f1 {*}See notes{}

Tested on (OS): Win 11

Notes:

• While initially I marked this as a regression, after being asked to check it seems the actual issue is that U6 default installed templates do not include BiRP, and this scene does not work with URP.
• I would argue this issue only affects U6 as the default is URP now, so the example scene should be updated to mention it is only compatible with BiRP (similar to example scene 28), or be updated so that it works with URP.
