Add support for passing keyword args to data in JS client

[hannahblair]

Description

This PR adds support for passing keyword arguments as well as positional args to the data param in the JS client. This is backwards compatible, so the two usages will work:

const result = await app.predict("/predict", ["Chewbacca"]);

const result = await app.predict("/predict", { name: "Chewbacca" });

Also adds unit tests.

The CodeSnippet.svelte API usage has been updated, which you can see here: https://huggingface.co/spaces/hmb/test_args

Closes: #7831

todo: need to update codesnippet.svelte

Just left one small comment but everything else looks great + works as expected!

Thanks @hannahblair!

Nice @hannahblair! Just 2 nits with regards to the code snippets:

• The code snippet itself looks good, but in the parameter table below, we should now put the name of the parameter, instead of the [0] to designate the positional argument
• We can also remove the comment // string in... as that information is included in the parameter table

Matching the Python code snippet and parameter table:

2. The RecordingSnippet.svelte code snippet still shows the positional format, would be great if we can update this as well:

Tested and looks good, will file another issue for the API recorder because it is broken in the release.
