Description

This PR removes the QrCode component.

The component was never tested within the preview, and only worked within a server-side render or direct call to render. That combined with the fact that the data-uri format isn't widely supported means that this just isn't ready to be included. This is not a breaking change because the component was never correctly exported from jsx-email (oops).

you probably need to run pnpm i and commit the lockfile update.
