Swap out Faker for @faker-js/faker

[kevin-mitchell]

After the "switcheroo" that was pulled with Faker, I imagine that it would be a good idea to switch Faker out for the accepted "official" fork of the original project.

See: https://fakerjs.dev/

My understanding is that the best way to approach this swap would be to wait for the 6.0.0 release of @faker-js/faker (as of this ticket being created the current package is 6.0.0-alpha.5), then "just" swap out the libraries.

In a very quick test I found that it seems pretty simple to swap out "old faker" for "new faker", although I followed these steps https://github.com/faker-js/faker#typescript-support to make TypeScript happy (this may be unnecessary).
