Description

Hi,

I'm adding a visual, multi-line example to the Align class docstring, as it previously had none.

Since a good example for Align requires imports and setup (like creating a Console and a Panel), I used the .. code-block:: python format for maximum clarity and user-friendliness.

I've also updated CHANGELOG.md and CONTRIBUTORS.md as requested by the contribution guidelines.
