Pull request overview

This pull request updates Varien_Image_Adapter_Gd2::save() to simplify redundant isset()/!isset() branches, addressing a PHPStan “isset.variable” warning and allowing removal of the corresponding baseline entry.

Changes:

• Simplified the save() parameter-branching logic by removing conditions that are implied by earlier elseif branches.
• Deleted the dedicated PHPStan baseline for the redundant isset() warning.
• Removed the deleted baseline file from the PHPStan baseline loader.
