🐞 Fix EfficientAD's pretrained weigths load path

[seyeon923]

📝 Description

• Downloaded and extracted EfficientAD's pretrained models' filenames are "pretrained_teacher_small.pth" or "pretrained_teacher_medium.pth"
• But, loaded pretrained models' filenames are "pretrained_teacher_EfficientAdModelSize.S.pth" or "pretrained_teacher_EfficientAdModelSize.M.pth", because of getting load path with string interpolation with model size enum itself.
• Fix load path interpolation to use associated enum value("small" or "medium")
• 🛠️ Fixes [Bug]: Using invalid pretrained weigths file path from EfficientAD #1965
