Model Registration Conflict in tiny_vit_sam.py

Hello,

I've encountered a recurring warning when working with the tiny_vit_sam.py script in the SAM repository. It seems like there's a conflict with model registration where models are being overwritten in the registry. This issue arises when different models with the same name are registered multiple times.

The script throws warnings indicating that it's overwriting models in the registry. This might lead to confusion or potential issues, especially in cases where different model versions are expected to coexist.

```

This is because the name being registered conflicts with an existing name. Please check if this is not expected.

I hope this information is helpful for resolving this issue. Thank you for your attention to this matter.

Reproduce the warnings from tiny_vit_sam.py and inspect the model-registration code around line 654, focusing on the listed tiny_vit model names. Determine whether repeated registration is expected and what behavior should occur when names conflict; done means the intended registry behavior is clear and the reported warnings or conflict are addressed.
