[Documentation] Language Switcher Does Not Override Browser Locale

[afarmerdev]

Description

When I visit the website, it automatically loads in Turkish based on my OS/browser language settings. However, when I manually switch the language to English, the change does not take effect. The interface remains in Turkish and does not update to English.
