AMP email `amp-accordion` documentation examples not working

[bdjang]

Description

Bug issue 1. All 6 amp-accordion preview examples for AMP email are not working correctly in the docs page.

• Expected behavior: when you click on the "Section 1", "Section 2", or "Section 3", it should drop down and display the text or image content.
• Current behavior: clicking on the different sections doesn't display the text or image content.

Bug issue 2. For the [data-expand] amp-accordion AMP email example, the "Open this snippet in playground" example is not working correctly.

• Expected behavior: "Expand section 1" button will expand and display section 1 content; "Collapse section 1" will collapse section 1
• Current behavior: Both buttons are not working.

The amp-bind script line is missing in the tag:

<script async custom-element="amp-bind" src="https://cdn.ampproject.org/v0/amp-bind-0.1.js"></script>

If you add that in, the amp-accordion example will work correctly.

Reproduction Steps

Bug issue 1:

1. Go to amp-accordion documentation page for AMP email
2. Click "Section 1", "Section 2", or "Section 3" for any of the amp-accordion examples. The sections are supposed to expand.

Bug issue 2:

1. Go to amp-accordion.example.4
2. Click on "Expand section 1" and "Collapse section 1" - both buttons are not working.
