Ensure collection version is populated in Hydrocron DynamoDB table fields

[nikki-t]

JIRA ticket https://bugs.earthdata.nasa.gov/browse/PCESA-3335

When doing some testing, I noticed that the collection_version field in the DynamoDB tables is empty. It looks like the collection_version variable is never set in the code that reads data from the shapefile name:

hydrocron/hydrocron/db/io/swot_shp.py

Lines 227 to 249 in efa0e3b

	collection = ""
	collection_version = ""
	for table_info in constants.TABLE_COLLECTION_INFO:
	if (table_info['feature_type'] in filename) & (table_info['collection_name'] in filepath):
	collection = table_info['collection_name']
	filename_attrs = {
	'cycle_id': filename_components[5],
	'pass_id': filename_components[6],
	'continent_id': filename_components[7],
	'range_start_time': datetime.strptime(
	filename_components[8],
	'%Y%m%dT%H%M%S').strftime('%Y-%m-%dT%H:%M:%SZ'),
	'range_end_time': datetime.strptime(
	filename_components[9],
	'%Y%m%dT%H%M%S').strftime('%Y-%m-%dT%H:%M:%SZ'),
	'crid': filename_components[10],
	'collection_shortname': collection,
	'collection_version': collection_version,
	'granuleUR': filename,
	'ingest_time': datetime.now(timezone.utc).strftime("%Y-%m-%dT%H:%M:%SZ")
	}
