Feature/multilingual footer

[joelson91]

What does this PR change?
This PR modifies the footer template to replace the static “Powered by” text with a dynamic variable that supports multiple languages. It introduces a new translation key for the footer text and updates the template to use this key, allowing the footer text to change based on the selected language.

What problem does it solve?
This change solves the issue of having a static footer text that does not adapt to different languages. By making the footer text dynamic and language-sensitive, it enhances the user experience for non-English speakers and ensures consistency across different language versions of the site.

Note: only the files i18n/en.yaml and i18n/pt.yaml have been updated to include the translation.
