Add FAQ for terminal getting messed up on panic

See https://discord.com/channels/1070692720437383208/1072907135664529508/1226403628202332255 for details

This should mostly point at resources to fix this

For the next person wondering, this has since been implemented in the default init:

let mut terminal = ratatui::init();

Per doc string:

/// This will create a new [DefaultTerminal] and initialize it with the following defaults:
///
/// - Backend: [CrosstermBackend] writing to [Stdout]
/// - Raw mode is enabled
/// - Alternate screen buffer enabled
/// - A panic hook is installed that restores the terminal before panicking. Ensure that this method
/// is called after any other panic hooks that may be installed to ensure that the terminal is
/// restored before those hooks are called.

so these docs should probably get updated to:
