JSON Tutorial missing centered_rect function definition

[oboyte]

Description

JSON Tutorial missing the centered_rect function definition, which is important for you to progress further through the tutorial.

Screenshots

Additional context

Although not crucial, some sections earlier on in the tutorial do lack some information which would be nice to have, like lacking some use declarations, whilst the code examples expect you to have.
One example is when you create a new terminal variable in Main.rs section let mut terminal = Terminal::new(backend)?;. However the page never imports ratatui::terminal::Terminal into scope. (Its inside ratatui::prelude, so I assume that was accidentally removed at some point)

You can find a centered_rect function here in ratatui or here in the json app source code.

I'm hoping to work through all the tutorials with a completely fresh state and ensure no information is missing. But that'll probably happen after the crates-tui tutorial is merged (#440).
