Example needs renaming to match lib name

[kattni]

One example begins with amg8xx_. It should begin with amg88x_ to match the lib name.

The lines including this file name in the docs/examples.rst file must also be updated to reflect the name change, e.g.:

.. literalinclude:: ../examples/current_file_name.py
    :caption: examples/current_file_name.py
    :linenos:

would be updated to:

.. literalinclude:: ../examples/current_file_name_changed.py
    :caption: examples/current_file_name_changed.py
    :linenos:

Shouldn't this actually be amg88xx_?

@makermelissa Yes. The PR is still open. I will have them fix it.
