feat: Show language switcher for guest users on navbar

[surajshetty3416]

• Language toggle option for guest users
• The server will decide the user's language preference using the "preferred_language" cookie
• Selected language will be remembered via "preferred_language" cookie stored in browser

• We can also use navigator.language: https://stackoverflow.com/a/8199791
• We may not need both localStorage and cookies. Perhaps only cookie with no expiry might suffice (can be retrieved in JS as well).

How will this work? From where will the user be able to switch the language?

Yep, was worried about the cookie getting cleared after someone logs in. But it works because we are not clearing preferred_language in clear_cookie method.

Before user enters their preference for the first time, we can take a good guess using this.

@surajshetty3416 is there any way to limit the languages shown? For example, I would like my website to be available in English and Russian only. I will take care to translate all the labels in these languages. The user experience would be very poor when selecting German as a language.

Yes, we have discussed this internally...
We finally decided to have it configurable in Website Settings where we can select languages to be shown in the language switcher.

@rohitwaghchaure is/will be working on this & other enhancements.

You can now disable Language document and it won't show up on the selector.
