Support Vite 8

Vite 8.0.0 was released on March 12, over three months ago. However, `qwik/package.json` still restricts the supported Vite versions to: ```json "peerDependencies": { "vite": ">=5 <8" } ``` Please consider updating support for new major versions of underlying dependencies more quickly. This would allow users to benefit from performance improvements, bug fixes, and new features sooner, while reducing the need to override peer dependency constraints.
