chore: bump sveltekit to v2 along with its dependencies

[Davidonium]

Tried using this library and since I recently bumped my project to sveltekit v2 I saw a warning, as seen in the issue #49.

This PR tries to solve the warning.

In the PR:

1. There are bumps to @svelteks/kit v2 and its surrounding dependencies. (The svelte 3 to 4 bump required some additional work on the setup of eslint).
2. Adds tabindex and role=button to avoid aria warnings to a div that was raising them.
3. Fixes package publishing so that dependants on this package don't receive this warning: https://github.com/sveltejs/vite-plugin-svelte/blob/main/docs/faq.md#missing-exports-condition

I would need some help with the version bumping on the actual library. Also the e2e tests are failing because there's a small difference of subpixels in the image sizes.

Not sure how you work but I am open to change anything, hope this helps maintain the library.
