Docs: Remove redundant @abstract tags from DocBlocks in WP_Image_Editor.

Since the affected methods are already marked as `abstract` in the function signature, these tags are unnecessary and add no new information.

Follow-up to [22094], [22510], [22619].

Props marian1, narenin, ankitmaru.
Fixes #63356.
