3.6.beta5: WorldEnvironment SpaceScreen shaders are broken

[ReanimatorXP]

Tested versions

• Reproducible in: 3.6.beta5
• Not reproducible in: 3.6.beta4, 3.5.2.stable

System information

Windows 10 - Godot 3.6.beta5 - GLES3

Issue description

Built-in shaders SSAO, SSR and DOF blur work incorrectly in GLES3. They strongly reduce lights from the light sources and completely ignore ambient light.

Steps to reproduce

1. Create new empty project
2. Add some meshes (e.g. CSG boxes)
3. Add Directional Light
4. Add WorldEnvironment node
5. Set up WorldEnvironment:
6. Set any light color in the Ambient Light tab (e.g. #a0a0a0 )
7. Enable any of Screen Space or DOF shaders

Presumably a duplicate of #91967 so already fixed.
I'll double check the project though.

Maybe we should leave #91967 open temporarily to prevent duplicates.

Yup this is fixed already, duplicate of #91967.
