Is there an existing issue for this?

Summary

Since Svelte is a compiled-time framework, the only way to use it as a "runtime library" would be to convert a Svelte component into a Web Component. It would be great if AppSmith could support Svelte framework for custom widgets/components.

Why should this be worked on?

Svelte is gaining popularity fast and is a pleasure to code with. Main reason for request: Svelte has "world-class" developer experience!
