Improve documentation

I'm a new user of supabase-swift, and relatively new to Swift as well so apologies if any of this is obvious.

I am seeing a deprecation warning when doing something like this

await supabase.database.from("users")

'database' is deprecated: Direct access to database is deprecated, please use one of the available methods such as, SupabaseClient.from(_:), SupabaseClient.rpc(_:params:), or SupabaseClient.schema(_:).

I grabbed this code from the Supabase website. All of the examples suggest doing DB queries like this. I can't find any examples of this new method.

https://supabase.com/docs/reference/swift/initializing

All of the examples on this page showcase DB access like supabase.database.from().

Describe the problem

The documentation is missing examples for the new way to interact with the Database. I notice there is a PR #341 that removes this method. Unfortunately I can't find examples of the new style of doing queries. I'm concerned that if this PR gets merged before the documentation is published, others like myself will be stuck on older versions of the lib until we figure out how to migrate our code.

Describe the improvement

Please update the Swift lib reference page with modern examples of how to run queries with the Supabase client.

Additional context

As a Swift/iOS beginner, it's hard to infer from the deprecation warnings what the correct way to use the library is. I depend on examples a lot, especially given how little I know the language. This may just be a me problem, but I imagine there are a lot of other beginners using this to build iOS apps.
