Update Cloduflare<>SvelteKit documentation once SDK supports Cloudflare

[Lms24]

SDK

JavaScript SDK

Description

Our current docs for using cloudflare pages with sveltekit are out of date and the instructed way of setting up the SDK makes SvelteKit throw a build error. This should be fixed once getsentry/sentry-javascript#14672 is merged and released so that we can use @sentry/sveltekit directly instead of @sentry/cloudflare.

Suggested Solution

Once getsentry/sentry-javascript#14672 is released, we should update docs to reflect the up to date way of using SvelteKit on CF pages.
