Proposed a property for an identifier for a company on the Comparably site, and it got created ✅

Seemed sensible considering that other similar sites (LinkedIn, Glassdoor) have their own company identifiers already, so might as well add Comparably to the list

With the property created, also got to linking loads of other existing company entries to their Comparably company pages (roughly 200+ at this point?)
