fix(svelte): widen typescript peer dependency range to allow v6

[ocavue]

Changes

A follow-up to #16471 and #16472

svelte2tsx@0.7.55 supports typescript v6, so we can also update the typescript peer dependency range in @astrojs/svelte.

Testing

CI should pass

A changeset file is added because we need to release a new version for @astrojs/svelte.
