Move inference snippets logic to inference package

[Wauplin]

Original slack message from @Wauplin (private link):

I have an annoying problem I don't know how to handle in @hugingface.js.
I'm working on updating the inference snippets under @tasks . Now that we have a makeUrl helper for each provider (see cohere example), I want to use it in the CURL snippets to display to correct URL (for now it's hardcoded here which is incorrect for some providers). To do that, I need to make @tasks depend on @inference . But @inference is already depending on @tasks especially to type inference inputs/outputs. Is this something npm/pnpm is able to settle (in Python it's not ^^).

The other solution I'm thinking about is to start having a @snippets package depending on both @tasks and @inference but I'd like to avoid that as much as possible 🙈 Any idea?

=> after some discussions we went for "let's move the snippets code to inference" which this PR does. @julien-c @coyotte508

⚠️ This is a breaking change for @huggingface.js/tasks. Will require to make a major release?

In practice I had to move only parts of the ./snippets folder:

• the type definitions + utils remains in @tasks since it is used to generate some local app snippets
• only the js/python/curl -specific parts are moved to @inference => i.e. only the logic to generate the snippets, not the helpers

EDIT: I just pushed d5fb4d6 to fix https://github.com/huggingface/huggingface.js/actions/runs/13636239608/job/38115630313?pr=1247:
=> Reverted it, the issue still exists 😕

I chose to set ES2022 as this is what's already defined for @tasks.

Works for me, though I still think we should merge those two packages...

This is a breaking change for @huggingface.js/tasks. Will require to make a major release?

I highly doubt anyone outside of HF was relying on the snippets being inside of tasks

For that matter, I doubt anyone outside of HF is importing tasks (it's not really a library or natural building block imo)

I'll merge as-is for now and I'll consider merging everything together if I ever need to move parts again
