PDF Gen - Add legal info to configs

As we implement the feature to display legal information at the PDF title. We need to add legal info for each PDF form to their configs.

**Format**:
will be added later (TBD)

**TODOs**:
- [ ] If it's not yet exist, then create a new option in `PDFConfigOption` Enum in utils.py called `LEGAL_INFO`
- [ ] Try to find legal info in [existing PDF forms](https://www2.gov.bc.ca/gov/content/employment-business/business/managing-a-business/permits-licences/businesses-incorporated-companies/forms-corporate-registry#forms) and use these information. Check what are the accepted format with Eason / Aimee
- [ ] Add legal info configs for these forms
- [ ] TBD
