fix: typo in PerceptualLoss MedicalNet warning message

[rtmalikian]

Problem

In monai/losses/perceptual.py line 115, the warning message for MedicalNet channel_wise has a typo:

warnings.warn(
    "MedicalNet networks supp, ort channel-wise loss. Consider setting channel_wise=True.", stacklevel=2
)

supp, ort should be support.

Proposed Fix

Correct the typo: "MedicalNet networks support channel-wise loss. Consider setting channel_wise=True."
