This pull request adds new overloads for the try_to_timestamp and try_to_date functions in both Java and Scala APIs, allowing users to pass the format as a plain String in addition to the existing Column-based approach. It also updates documentation and test cases to reflect these changes and clarify usage. These improvements make the APIs more flexible and user-friendly.

API Enhancements

• Added new overloads for try_to_timestamp and try_to_date in Functions.java and functions.scala that accept the format as a String, making it easier to use these functions without needing to wrap the format in a Column (lit). [1] [2] [3] [4]

Documentation Updates

• Updated JavaDoc and ScalaDoc comments for try_to_timestamp and try_to_date to clarify the accepted types for the format parameter and to provide examples for both the Column and String overloads. [1] [2] [3] [4]

• Revised code examples in documentation to show usage with both lit() and plain String format arguments for better clarity. [1] [2] [3] [4]

Test Coverage

• Added new test cases in both Java (JavaFunctionSuite.java) and Scala (FunctionSuite.scala) to verify the new overloads work as expected and produce the same results as the existing Column overloads. [1] [2] [3] [4]
