Add static methods for update, insert, and delete in DapperEntityORM repository

[LuigimonSoft]

Currently, the DapperEntityORM repository lacks static methods for update, insert, and delete operations. This creates an inconvenience for developers who have to create an instance of the repository to perform these operations.

Adding static methods to the repository will make it more user-friendly and save developers time and effort. Static methods can be called directly without the need to instantiate the repository class.

Therefore, I propose that we add static methods for update, insert, and delete operations in the DapperEntityORM repository. These methods should have the same functionality as the instance methods and be implemented in a way that is consistent with the existing codebase.
