Remove non-existent MetaCLIP 2 L/14 checkpoint

[voidism]

This PR removes the MetaCLIP 2 L/14 model checkpoint entry that does not exist anymore.

• This model was invalid / not hosted anymore: https://huggingface.co/timm/vit_large_patch14_clip_224.metaclip2_worldwide
• Keeping the entry may cause confusion for users trying to load the model
• Other MetaCLIP 2 checkpoints are untouched

This change ensures that only available and verified checkpoints remain in the model registry.
