Steps to reproduce:

1. Create a new project
2. Import attached png CherryTree_01_T_A.png
3. Press Cmd+K to open Global Search
4. Search "Cherry Tree" and click on the png result
5. View this in the Global Search inspector
6. Click the Open Reference (?) button next to Cherry Tree_01_T_A (Texture 2D)

Actual results: Opens a link to missing documentation. [https://docs.unity3d.com/6000.0/Documentation/Manual/class-Texture2D.html]

Expected results: Links to relevant documentation link.

Reproducible with versions: 6000.0.8f1

Couldn't test: -2022.3.33f1, 2021.3.38f1 - couldn't find any editor UI which opens a reference for Texture 2D. Open reference was not available in Global Search in these versions.-

Update: this issue can be verified on Unity 2021.3 and 2022.3 by including the attached 
CreateTextureMenuItem.cs and creating a texture asset. Inspecting that asset has the same issue when clicking the "?" to go to the manual.
Tested on (OS): MacOS

Notes:

• Set to not a regression as I could not find a way in earlier versions to open reference for Texture 2D - if I missed something, contact me and I can test further if needed.
