Svelte Compatibility

[MrVauxs]

This is more of a "keep in mind" than an actual bug report, but both eslint-plugin-svelte and svelte-eslint-parser have -next versions that support the latest Vite 6 and Svelte 5 packages, amongst other things like latest version of eslint.
However, due to them being -next I don't know if it would be desirable to add them to this package. It would probably be best as a || operator, if anything.

For now, I am unfortunately have to --force npm to install these higher dependencies, with eslint-config being the cause.

If fixing that problem is desirable despite these packages being technically prereleases, I can make a PR.
