Fix specifying media uris for google vertex

[mattmatters]

Changes data => fileUri.

Thanks @mattmatters! I haven't looked into this but I'd love some more information. My guess is that the file data could be Base64 encoded (so the file is uploaded directly), or it could support the fileUri for where it could be downloaded from.

If so, I'm hesitant to break a potentially working solution for some people.

Oh sorry I should have supplied more details, I can check on inline data but even just having the data key set at all results in the vertex api returning a 400 error saying that an unknown key data is set. So I don't believe that this has worked for anyone yet.

I did leave the inline data field alone though above it as I haven't been working with inline data and didn't want to mess with that for folks.

Just to follow up here I tested with setting inline data to the image_url type and it also does not work. I don't believe this codepath has ever worked for vertex ai.
