Home page is not translated when changing locale

[basketshoe]

The translated docs home page (docs.sidestore.io/[language-code]) is not being translated when switching locales.

Reproduce steps:

• Go to https://docs.sidestore.io/
• Switch to any locale using the top right dropdown menu

Expected result:

• The home page is translated to the selected locale

Actual result:

• The home page does not change

Solution:

• use yarn write-translations --locale [language-code] to write translations into i18n/[language-code]/ so that the homepage and sidebar dropdown menu titles are translatable
