Repro:
1. Create new project.
2. Install Shader Graph package.
3. Assets > Create > Shader Graph > BuiltIn > Lit
4. Open the newly created Shader Graph

Expected: No errors in console.
Actual: Error and 6 warnings in console. Can still use ShaderGraph.

Having trouble with regression testing this as I can't get all package versions downloaded.
However, these errors do not occur in 2021.3.6f1 with 12.1.7, so marking as regression.
