(DOCSP-39501): Consolidate Quick Start page

[dacharyc]

Pull Request Info - SDK Docs Consolidation

Jira ticket: https://jira.mongodb.org/browse/DOCSP-39501

Staged Page

• Quick Start
• SwiftUI Quick Start: Existing content ported over with Realm naming and ref updates
• Flutter Quick Start: Move existing Flutter-specific content out of quick start to this relevant section
• Unity Quick Start: Existing content ported over with Realm naming and ref updates

Adding a note here to capture this in the PR record:

• Product has made the call to remove Java SDK info from our "getting started" content (here and the Install page), so I've removed the Java and Kotlin (Java SDK) examples from the consolidated quick start page.
• Based on relatively low usage of the Java SDK Quick Start with LiveData page, and the need to update it to show Kotlin SDK or at the very least not Partition-Based Sync, I've checked with engineering and product and am removing this page from the docs. It doesn't seem worthwhile to continue to incur the maintenance cost.
