Reorganize SvelteKit Manual Setup page

Description

The SvelteKit quick start guide (manual setup) (see PR) contains advanced topics that are not part of the quick start (and are also not covered by the wizard setup). The goal of this task is to move detailed content to other, more suitable pages and streamline the content that should remain in the quick start guide.

Similar issue for Next.js: #12487

Suggested Solution

• identify the information we want to move away from the quick start guide and find new locations for this information (ideally, add to existing pages)
• optimize the content we want to remain in the quick start guide

Content

Source Maps Upload

• update quick start guide to align with content on Source Maps in other guides
• update SvelteKit Source Maps page with content (so we don't lose anything)

Auto-Instrumentation

• (this is about sentrySvelteKit() in vite.config.)
• add these to the Build options page
• in the quick start guide, we can set a link to build options in Next Steps

Configure CSP for client-side fetch instrumentation

• move to Troublshooting
• in the quick start guide, we'll create an Expandable (because this is only relevant for older svelteKit versions) and then link to page

Manual Instrumentation

• wrapLoadWithSentry wrapServerLoadWithSentry wrapServerRouteWithSentry -> API page
• in the quick start guide, we can set a link in Next Steps

Cloudflare Pages Configuration

• create an Expandable (this is important for some users, so it should stay in the guide)
