Rename Supabase C# Packages to Conform to Nuget's Naming Conventions

[acupofjose]

As mentioned in the discussion here:

The currently released libraries on Nuget do not conform to the naming conventions expected in a nuget package. The Nuget packages for supabase-csharp and all its dependencies should be depreciated (as Nuget does not support renames) and new packages released according to their new names.

Proposed names:

Existing Package	New Package
supabase-csharp	Supabase
postgrest-csharp	Supabase.PostgREST
gotrue-csharp	Supabase.GoTrue
realtime-csharp	Supabase.Realtime
storage-csharp	Supabase.Storage
functions-csharp	Supabase.Functions
core-csharp	Supabase.Core

As this would require users to install separate packages and includes namespace changes (specifically for postgrest-csharp and gotrue-csharp) this will be held until the next Major Release.
