Add matched type in PersonEnrichmentResponse interface

[muzzamilr]

Description of the change

• Update the PersonEnrichmentResponse interface by adding "matched" type, because person enrichment api returns matched array of strings when passed a param 'include_if_matched: true' and it's type was not proper in the sdk and I was unable to destructure "matched" or use it like response.matched in typescript.
