Slideshow Block: Pagination added in 11.7 beta doesn't work with AMP

### Impacted plugin

Jetpack

### Steps to Reproduce

1. Start with a site running the 11.7 beta.
2. Install and activate the [AMP plugin](https://wordpress.org/plugins/amp/).
3. Add one or more slideshow blocks to a post or page; for each block, add six images.
4. View the AMP version of the page on the front-end.

### A clear and concise description of what you expected to happen.

I expected the updated pagination to continue to be AMP (things like the slideshow advancing still work as expected with AMP!).

### What actually happened

The pagination doesn't update as you page through the photos.

Also, if you have more than one slideshow on the page, the pagination starts at an offset number (1/6 for the first one, 2/6 for the second one...).

Lastly, the slideshow has some very minor display issues when AMP is enabled (like the previous/next buttons are a lot closer to the edge).

### Browser

Google Chrome/Chromium, Mozilla Firefox, Apple Safari

### Platform (Simple, Atomic, or both?)

Atomic, Self-hosted

### Reproducibility

Consistent

### Severity

Some (< 50%)

### Available workarounds?

Yes, easy to implement

### Workaround details

Disabling AMP on a per post/page basis fixes the issue, but as it does impact existing slideshows they would need to be found on a site using AMP and have AMP disabled on those pages.

Start by reproducing the issue with Jetpack 11.7 beta, the AMP plugin, and multiple slideshow blocks containing six images each. Compare the AMP and non-AMP front ends; done means pagination updates as slides advance, starts independently for each slideshow, and the AMP controls no longer have the reported display issues.
