fix(metadata): use original casing for model IDs in page titles

[emharsha1812]

This PR resolves Issue #83, which addresses model IDs being incorrectly uppercased.
In apps/webapp/app/[modelId]/page.tsx, the generateMetadata function was applying .toUpperCase() to the model ID from the URL/page.tsx].

Fix

The .toUpperCase() method call was removed from params.modelId in the generateMetadata function within apps/webapp/app/[modelId]/page.tsx/page.tsx]. This ensures the page title respects the original casing of the model ID.

Testing

Tested locally. Showed no errors

thanks! some notes-

1. I think we uppercase model ID in a few other places as well, which I would like to update:

• model dropdowns
• breadcrumbs (? not 100% sure)

2. the original issue (which i should have written a LOT more detail) was also about accessing the models via URL. for example, https://www.neuronpedia.org/GPT2-SMALL does not work, but https://www.neuronpedia.org/gpt2-small does work. both should actually work since model names should be case insensitive.

3. also - can you attach screenshots as verification as well? thanks!

addendum to 2) - thsi should also be the case in the API
