feat: adds support for svelte 5

[sverweij]

Description

• updates the svelte compile call to include an empty object as a 2nd parameter.
  This is required for svelte 5 and svelte 4 seems to ignore it so it seems we're in luck and don't need funky branching.
• Adjusts the supported compiler range for svelte
• Adjusts the integration & unit tests to expect svelte 5 output

Motivation and Context

Svelte 5 seems to have become stable and in their release notes they encourage users to upgrade.

Also fixes #962
