Add a form in the side panel to export documents to the Cloud

[Kerollmops]

This PR adds a new form for uploading documents to the Cloud (or elsewhere). You can abort the upload if it takes too long or the URL or API key is wrong. The interface shows the progress with a simple percentage on the upload button.

It uses the new export route to perform this operation.

@Kerollmops I've fixed the CI and removed the duplicated code.
Can you please check that this is still working as expected? Then we can merge it and release 🙏

I've tried to use this feature but I'm getting a 404 error, not sure why BTW 🤔

You are not using the right version of Meilisearch, and the version you have doesn't expose the /export route. Try with Meilisearch on the main branch. You'll also need another instance running on another port. I'll try the feature now 😃

Ah yeah that makes sense now that you mention it 🤣
I'll let you test it then, it seems a bit complicated to test it on my side 🙏

Hey @mdubus 👋 After thorough testing, the PR looks good and works perfectly with and without embeddings. The progress works excellently and is helpful. Nice work to both of us ✅ 🙏
