Hello! I've noticed something unusual when checking this PR at commit
373231062873e1d2c94f3b76fe13f13b656f87b7:

• The page pages.pt_BR/common/kubectl-delete.md is outdated, based on the command contents itself, compared to the English page.
• The page pages.pt_BR/common/kubectl-delete.md has a more info link that does not match the one in the English page. 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.

Hi @thiagonazario!
The link in the > More information: section must match the English version exactly. Please check pages/common/kubectl-delete.md and copy the link from there.
The examples differ from the current English page. Please ensure your translation corresponds 1-to-1 with the English version.
