[BUG] pkgrepo.managed does not report changes when it cleans a .list

[OrangeDog]

Description
If the given line is already present in the file, but clean_file is true, Salt will clean the file but not report any changes.

Setup

salt repo:
  pkgrepo.managed:
    - name: >
        deb [arch=amd64 signed-by=/etc/apt/keyrings/salt-archive-keyring.gpg]
        http://packages.broadcom.com/artifactory/saltproject-deb/
        stable main
    - file: /etc/apt/sources.list.d/salt.list
    - clean_file: true
    - key_url: https://packages.broadcom.com/artifactory/api/security/keypair/SaltProjectKey/public
    - aptkey: false
