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

The `slideshow `arrow buttons listener should be reversed too for RTL not only the arrows direction

Google Chrome/Chromium

_No response_

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

Simple

Consistent

### Severity

Some (< 50%)

### Available workarounds?

No but the platform is still usable

### Workaround details

Making custom blocks / download

Start by reproducing the slideshow block in an RTL locale using the listed steps, then locate the Jetpack slideshow block implementation and its arrow-button listener. Confirm that each arrow moves the slideshow in the expected RTL direction, and verify the behavior in Chrome before and after updating the page.
