feat: localize new taxonomy names

- Tag links now use the actual taxonomy name for the URL and the displayed label is wrapped in a translation macro instead of the previous placeholder-based logic.
- Simplify the taxonomy tag URL by passing the name directly and add translation support for the tag label.
- Introduce a new taxon_name_i18n variable to translate the taxonomy name and swap in this localized value for the page title and “See all” link, while also simplifying the all-taxa URL by passing taxonomy.name directly to get_url.
