guix upgrade command does not accept a list of packages

Guix documentation says that `guix upgrade` is an alias for `guix package -u`, but the latter can upgrade a list of packages, while the former fails.

## Steps to reproduce

1. guix pull

2. guix upgrade --dry-run

3. Pick two packages from the list shown in (2), say, packages A and B

4. guix upgrade A B

## Expected result

Packages A and B are upgraded.

## Unexpected result

Step 4 fails with the following message:

guix upgrade: error: B: extraneous argument

## System information

Using guix 0ae0efd with the Guix System.
