PR Summary

• Removal of reset Function and Addition of str_replace
  In the file DMLQueryBuilder.php, we previously had a function called reset. This function has been removed in order to improve our code. Additionally, a new feature called str_replace has been introduced, which helps with replacing certain parts of a string with different information.

• Refactoring of upsert Function
  Also in the DMLQueryBuilder.php file, the upsert function, which helps in either updating already existing data or inserting new data if it does not exist, has been restructured and simplified for better performance and readability of code.

• Updated Function Description for prepareInsertValues
  For the prepareInsertValues function in DMLQueryBuilder.php, the return type hint, which indicates the type of value that the function returns, and the comments, which give a general explanation of what the function does, have been updated for better understanding.

• Additional Test Case for upsert Function
  Lastly, in the QueryBuilderProvider.php file, an extra test case has been introduced for the upsert function, to ensure its functionality and correctness under various scenarios.
