Merged PR 48049: Refactor getRequest() in EmailCapturePlugin

## What's being changed

A plugin to a controller in the Email module.

## Why it's being changed

- Using `$this->getRequest()` in controllers is not allowed - we have to use `$context->getRequest()`.

## How to review / test this change

- Put a breakpoint in the plugin
- Start a chat
- Enter an email in the newsletter input
- After submit the email should be picked up in the plugin via an AJAX request
