feat: add Web Hosting FTP/SSH landing page in all locales (#262)

* feat: add Web Hosting FTP/SSH landing page in all locales

* docs: proofreading FTP/SSH landing page — reword orientation block across locales

Reword the "find the right guide" paragraph into a question-based format
(no section-title duplication) on all 7 locales, drop the "(Mac)" qualifier
on the Cyberduck label (the guide also covers Windows). Fix the pt title
(Alojamento web, consistent with the body and sibling guides) and the EN
"for your needs" wording.
