Catch delta table not found error

[milocress]

when the delta table isn't found, surface this error to the user.

Could you add a unit test in test_convert_delta_to_json.py please?

The docformatter hook runs without error locally, it grates like sandpaper against my soul that this hook would run differently on the server.

I think it's cool that docformatter won't tell me which file is incorrect, it's like a fun little scavenger hunt.

approving from foundry side. please make sure you and jane agree on the unresolved conversation before merging
