Updated IRepository<TEntity> to remove generic type parameters
from CreateAsync methods, now directly accepting TEntity.
Corresponding changes made in DbRepository to align method
signatures. Implementations still throw NotImplementedException.
Updated the IRepository<TEntity> interface to include an optional CancellationToken parameter in the asynchronous methods: CreateAsync, ReadAsync, UpdateAsync, and DeleteAsync. Modified the DbRepository<TDbContext, TEntity> class to align with these changes, ensuring method signatures are consistent with the interface.
This commit introduces a new `DbRepository` class implementing the `IRepository<TEntity>` interface, providing asynchronous methods for CRUD operations. The previous CRUD repository registration in `DIExtensions.cs` has been removed, indicating a shift in repository management. A new static class `DependencyInjection` has been added to facilitate the registration of `DbRepository` with the service collection, enhancing modularity and flexibility in database interactions.
