Hi! Currently, there is not an easy way to learn about the NeMo Curator version installed (there are work arounds).

Therefore, I think it would be great to incorporte the property nemo_curator.__version__ to the library.

In addition to that, it should be great to add it to the command line scripts when invoked with the --help argument.

Currently, when invoking, for instance, add_id --help, the following text is displayed:

usage:
Adds unique identifiers to each document in the dataset.
Creates a new ID field with name specified by the argument
"--id-field-name" within each json.
...

Maybe, changing it to something like:

NVIDIA NeMo Curator -- v3.2.1

usage:
Adds unique identifiers to each document in the dataset.
Creates a new ID field with name specified by the argument
"--id-field-name" within each json.
...

Hope it helps!
Miguel
