fix(web): replace deprecated $app/environment with $app/env in SvelteKit integration

[aynavbar]

Replaces the $app/environment import in packages/web/src/sveltekit/index.ts with $app/env.

$app/environment was deprecated in SvelteKit 3 in favor of $app/env and is scheduled for removal in SvelteKit 4:
https://svelte.dev/docs/kit/$app-environment

Migrating now avoids a deprecation warning for SvelteKit 3 users and a breaking import when v4 lands (though it's already breaking my prod build). New module reference: https://svelte.dev/docs/kit/$app-env

Changes

• packages/web/src/sveltekit/index.ts: import [browser/dev/etc.] from $app/env instead of $app/environment

Compatibility note

• This package still supports SvelteKit 2, where $app/env may not exist. I'd appreciate guidance on whether to bump the peer range, wait, or support both.

I also sent feedback through the docs page, which shows the same outdated import.
