fix(sveltekit): Add import attribute for node exports (#16528)

This patch changes the `node` export in the `package.json` file to include
an `import` version (similar to the other exports) to fix
sveltejs/kit#13869 .

In SvelteKit, we're now bundling dependencies on the server that specify
SvelteKit as a dependency or peerDependency. This has caused an issue
where builds with `@sentry/sveltekit` were being bundled incorrectly.
Adding the `import` attribute fixes this so that Vite resolves to the
ESM build of Sentry.
