[api] add redirect for translated quick-starts

This commit proposes to redirect translated api quick-start
documents, like the similar way as
docs.o.o/api/quick-start/content/ is redirected to
developer.o.o/api-guide/quick-start/ page.

Currently the following four language versions are applied
: de (German), ja (Japanese), ko_KR (Korean), zh_CN (Chinese).
