Subject: [PATCH] nip05: rename nip05 verification to nostr address

nip05 identifiers and nip05 verification is too confusing, and also
wrong. Let's use the "nostr address" terminology.

Suggested-by: Derek Ross
Suggested-by: Semisol <hi@semisol.dev>
Changelog-Changed: Rename NIP05 to "nostr address"
