Introducing Versatile IO Components: JSON Viewer, DictionaryIO, and InputListIO (#1822)

In our ongoing commitment to enhancing user experience and streamlining
data interaction, we are thrilled to introduce a trio of powerful IO
components: JSON Viewer, DictionaryIO, and InputListIO. These components
are meticulously crafted to empower developers with seamless data
handling capabilities, enabling efficient processing and visualization
of JSON data structures, dictionaries, and input lists.
