[bug#58621] [PATCH 1/3] import/utils: spdx-string->license: Fix incorrect docstring.

[Philip McGrath <philip@philipmcgrath.com>]

The result of 'spdx-string->license' is a symbol, not a license object.

* guix/import/utils.scm (spdx-string->license): Fix docstring.
(license->symbol): Mention 'license:' prefix in docstring.
