Visual Effects Template search does not return custom Templates when searching by the middle of the name

Steps to reproduce:

1. Create a new HDRP project
2. Create a new Empty VFX Asset (Create -> Visual Effects -> Visual Effects Graph -> Empty VFX)
3. Select the new Asset and enable 'Use as Template' in the Inspector
4. Change the Name to "Head"
5. Open the "Create a new VFX Asset" window (Create -> Visual Effects -> Visual Effects Graph)
6. In the "Create a new VFX Asset" window, search by "ead"
7. Observe the search results

Actual results: Only the "Head & Trail" Default Template is displayed

Expected results: "Head & Trail" and "Head" Templates are displayed

Reproducible with versions: 6000.5.0a5, 6000.5.0b3, 6000.6.0a2

Can’t test with versions: 6000.0.72f1, 6000.3.12f1, 6000.4.2f1, 6000.5.0a3 ("Create a new VFX Asset" window doesn't have search functionality)

Tested on (OS): Windows 11 Pro (25H2)
