bug#72273: 30.0.60; use-package installing package from both vc and archive versions

[Juan Palacios]

Start Emacs with the following command:
emacs -Q --init-directory=/tmp/emacs

Evaluate the following code:
(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/"))
(use-package restclient
  :vc (:url "https://github.com/abougouffa/restclient.el" :rev :newest))

Both the vc and the melpa versions of the package are installed. When
inspected through list-packages:
- The vc one has the latest commit hash in the list Version column.
The package details (pressing RET) shows Version as 0.
- The melpa one has 20231010.1327 in both Version fields.

Note that some package attributes, such as Version and
Package-Requires, are missing in restclient.el.

bug#72273: 30.0.60; use-package installing package from both vc and archive versions

[Juan Palacios]

Apologies. the code to reproduce the issue in the previous message
contains semicolons. Here is the corrected version:

(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/"))
(use-package restclient
  :vc (:url "https://github.com/abougouffa/restclient.el" :rev :newest))

Note that even I'm using use-package to trigger this behaviour, I
believe it could also be reproduced by using package-vc-* instead.
