How to reproduce:
1. Open any project
2. Put the attached “SubstanceArchiveFile.sbsar” file into the asset folder
3. Observe the result in console

Actual result: Unity shows an outdated warning message “<…> you will need to install Allegorithmic's external importer <…>”
Expected result: Unity shows up to date warning message

Reproducible in: 2023.1.0a1, 6000.0.65f1, 6000.3.3f1, 6000.4.0b3, 6000.5.0a4

Reproducible on: Windows 10 (by user), Windows 11
Not reproducible on: No other environments tested

Notes:
- When adding an .sbsar file to the assets folder, there is a warning "Built-in support for Substance Designer materials has been removed from Unity. To continue using Substance Designer materials, you will need to install Allegorithmic's external importer from the Asset Store." This warning is no longer accurate.
- Allegorithmic was acquired by Adobe, and the plugin is now named "Substance 3D for Unity" and is published by "Adobe Substance 3D" at https://assetstore.unity.com/packages/tools/utilities/substance-3d-for-unity-213208.
