fix: change applicant ownership tenant to lessee

[augustlindemer]

Schema change to align with content. The correct term for a leaseholder with interest in land is lessee, not tenant. Agricultural tenants are a wholly separate issue and not affected by this fix.

Thanks @augustlindemer & welcome to schemas land 🙂

Jumped on branch with two small minor additions here:

• We're temporarily maintaining a prototypeSchema, in addition to orginal application, which is the upcoming v1 "next" preview of sorts - so I've made sure to update language there too (currently means lots of duplicated definitions we need to clean up)
• The schema repo relies on a commit hook to also automatically generate the .json files from the TypeScript which isn't triggered when editing via the web, but is when commiting locally via GH Desktop or CLI
