When adding SettingsIconGenerator to a watchOS target, compilation fails with:
'UIGraphicsImageRenderer' is unavailable in watchOS

The package uses UIGraphicsImageRenderer, which is unavailable on watchOS.

Steps to reproduce:

1. Add SettingsIconGenerator via Swift Package Manager.
2. Link the package product to a watchOS app target.
3. Build the watchOS target.

Version: SettingsIconGenerator 2.1.0
