fix(block): fix crash on empty right aligned title (#933)
- Simplified implementation of the rendering for block. - Introduces a subtle rendering change where centered titles that are odd in length will now be rendered one character to the left compared to before. This aligns with other places that we render centered text and is a more consistent behavior. See https://github.com/ratatui-org/ratatui/pull/807#discussion_r1455645954 for another example of this. Fixes: https://github.com/ratatui-org/ratatui/pull/929
