For .blend files, the rightclick menu entry should display 'New/..' as usual, but it instead displays 'Show in File System' (functionality is not impacted)

### Steps to reproduce

Have a .blend file and some other asset (or a folder), rightclick both, notice the difference in the 'new' submenu labeling.

### Minimal reproduction project

Any blend file and any other asset will do, but if necessary i can upload random stuff.
