feat(i18n): add multilingual support for author data files

Hugo doesn't natively merge language-specific data directories with the default data. Add a `get_authors_data` partial that manually
looks up `data/<lang>/authors/` and deep-merges translated fields
on top of the default data/authors/ profiles.

Centralizes all `site.Data.authors` access through this new partial
so author names, bios, roles, and other fields can be translated
per language while inheriting non-translated fields from the default.
