Hello! I've noticed something unusual when checking this PR at commit
23debb2b0bce87f198a668a098a586c29be6521f:

• The page pages.ar/common/docker.md is outdated, based on the command contents itself, compared to the English page.
• The page pages.ar/common/docker.md has a more info link that does not match the one in the English page or the template. Please check the "More information:" translation as well using https://github.com/tldr-pages/tldr/blob/main/contributing-guides/translation-templates/more-info-link.md.

Is this intended? If so, just ignore this comment. Otherwise, please double-check the commits.
