Purpose of the task is, We saw that users encounter difficulties
while installing languages so improve the user onboarding experience
when user wants to install a new language.
So in this commit,
- Change the load langauge wizard title as 'Add Language' and rename
the button as 'Add'
- Removed documentation link as it is not up to date
- Added the 'Add language' button to general settings and it will open
the wizard to load the languages. and move the 'manage language' button
to the debug mode.
- After install added button 'switch to (lang) & close' to switch to
newly added language.
