HelpBox visuals in the "Shader Graph" settings window are not aligned with the latest style guide

Steps to reproduce:

1. Create a project
2. Go to "Edit" -> "Project Settings" ->"Shader Graph"
3. Resize the window
4. Observe the displayed help box UI and its behaviour

Actual results: The icon in the help box section is too big. Text moves. "Read more" position is not right

Expected results: Help box section should be updated according to the latest designs
 

Reproducible with versions: 6000.5.0a3

Tested on (OS): macOS - Tahoe 26.1

Notes: New UI changes are valid from U6.5
