Fix Chinese input issue in TextField by enabling isDelayed

Fixed an issue where Chinese IME candidate characters were being incorrectly inserted into TextFields (PackageDesc, GroupDesc, etc.), causing garbled text like "默认包baobabmo'rmom".

The fix sets `isDelayed = true` on all TextFields in AssetBundleCollectorWindow, which defers value change callbacks until the user completes input (by pressing Enter or losing focus), thus avoiding interference from IME candidate characters.

Modified TextFields:
- PackageName
- PackageDesc
- GroupName
- GroupDesc
- GroupTags
- User Data (collector)
- Asset Tags (collector)
