Standardize `text_field`, `id_field`, etc. terminology

As I've worked on several NeMo Curator functionalities, I've been a bit annoyed that our parameter names aren't consistent across different modules.

For example, text_field, input_text_field, text_column, text_column_name, input_json_text_field, dataset_text_field, input_field, input_json_field, etc. all mean the same thing semantically lol. Let's standardize it to just text_field.

Same with id_field and possibly others.
