`command-model generate-from-swagger` fails in providing list modnames

when running `command-model generate-from-swagger`, for example `aaz-dev command-model generate-from-swagger -a ./aaz --sm ./azure-rest-api-specs/specification/networkcloud -m networkcloud --rp Microsoft.NetworkCloud --swagger-tag package-2024-07-01`, it'll break with following error:
File "/home/anna/clones/nc-interfaces/env/lib/python3.12/site-packages/schematics/transforms.py", line 174, in import_loop
raise DataError(errors, data)
schematics.exceptions.DataError: {"modNames": ["Couldn't interpret '['networkcloud']' as string."]}
