'@clerk/shared': patch

Polish the missing/invalid key error copy: drop the two-space indent before the `npx clerk@latest init` command (it rendered as a stray space in browser error overlays), start the follow-up sentence with the command name instead of "It" so the sentence stands on its own, and reword "Requires no Clerk account or login" to "No Clerk account or login required".
