* refactor: adjust merge_data operations to use langflow.schema.DataFrame
* Update Merge Data component name and description
* [autofix.ci] apply automated fixes
* refactor: enhance data merging logic in DataMergerComponent
- Improved type hinting for combined data structures to enhance code clarity.
- Streamlined the concatenation and merging operations to ensure consistent handling of string and object types.
- Updated the logic to correctly append values to lists when merging data inputs, improving data integrity in the merging process.
* revert merge data changes
* add data merger component
* refactor: remove DataMergerComponent and clean up imports
- Deleted the DataMergerComponent to streamline the processing components.
- Updated the __init__.py file to reflect the removal of the DataMergerComponent from the exports.
* refactor: enhance MergeDataComponent with new merge operations
- Introduced a new enum, MergeOperation, to define various data merging strategies: CONCATENATE, APPEND, MERGE, and JOIN.
- Updated the merge_data method to return a DataFrame instead of a list of Data objects, improving data handling.
- Enhanced input validation to ensure a minimum number of data inputs are provided.
- Streamlined the merging logic to support different operations, improving flexibility and usability of the component.
