Companies altered from LTD in COLIN to BEN in Modern have incorrect share structure

- Based on Ops - https://sbc-registries.atlassian.net/jira/servicedesk/projects/ITOPS/queues/custom/52/ITOPS-289982
- Such companies are missing the word "Shares" in the shares description.
- This is caused by an error in the Jupyter Notebook used to migrate the data.

To Do List:
- [ ] Add 'shares' to impacted company share class name
- [ ] Add correction ledger with wording: Share class(es) corrected to reflect the word ‘shares’ at the end of name

List of impacted companies (all will be in modern): [ben_comp_with_no_share_word.xlsx](https://api.zenhub.com/attachedFiles/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBBOS9RRGc9PSIsImV4cCI6bnVsbCwicHVyIjoiYmxvYl9pZCJ9fQ==--ada2a21f1b2402c0da25497c038d8b9997ca15dc/ben_comp_with_no_share_word.xlsx)
