Verify - Add missing ULC, Credit Union and LLC request entity types

## Description
There are a few request entity types missing. These need to be added to the UI and also some backend work will be required to map back to Names oracle database.

Add:
- [x] Change (alter) the business type / BC / Unlimited liability company to a limited company
- [x] Change (alter) the business type / BC / Unlimited liability company to a benefit company
- [ ] Amalgamate two or more / BC/ Credit Union
- [ ] Amalgamate two or more / Extraprovincial (Internationally based) / limited liability company

### Overview:
Alteration of ownership filings in COLIN use incorporation NRs for the type of entity being created. E.g. to alter from ULC to BC Corp, you would use a BC Corp incorporation NR. The same could be done in the new system for ULC to Benefit company alterations. This leads to confusion since the Name Request UI will present distinct options for these name types, but then by the time they make it to the back end and NRO, they are viewed as generic incorp types with no indication of being used for an alteration. I believe this dilemma exists for other NR types too.
Based on the above:
ULC to BC Corp would use request_type_cd 'CR' in NRO
ULC to Benefit Corp would use request_type_cd 'BC' in NRO

Amalgamation of Credit Unions takes place on COBRS to the best of my understanding. It appears to use the request_type_cd of FI which is Financial Institution (BC) - Incorporation. There isn't a separate request type for FI amalgs.

Amalgamation of EP LLC takes place in COLIN today (AMALL). It uses the XCR request_type_cd
