[bug#49531] [PATCH core-updates v2 3/4] import: crate: Emit new-style package inputs.

[Sarah Morgensen via Guix-patches via <guix-patches@gnu.org>]

* guix/import/crate.scm (maybe-cargo-development-inputs)
(maybe-cargo-inputs): Wrap PACKAGE-INPUTS in unquoted 'list'.
* tests/crate.scm ("crate->guix-package")
("cargo-recursive-import")
("cargo-recursive-import-hoors-existing-packages"): Adjust accordingly.
---

Looks like I missed the version in the test inputs. The tests passed before too
though; it looks like the expected output (or at least the symbols in the
expected output) needs to be quoted in some way, or else match just takes any
value in that slot.
