Rename index.html to index.svelte

[PaulMaly]

Seems, if we want to use Svelte components in different environments we should use a custom extension to prevent any conflicts with existing webpack/rollup configs.

Hi @PaulMaly!

Yeah, it's a bit of a hassle. If we change to .svelte it will stop working for others which have a working configuration for .html.

I'm subscribing to the Convention for packaged components to export uncompiled templates issue and will implement that when something generic is implemented.

I think it's very simple to fix that )))

test: /\.(html|svelte)$/,

I changed to the .svelte file extension in 2.0.0.
