Accessibility: Errors and Success messages not announced to screen reader users

Hello,

The plugin’s forms use a span to provide error and success messages to users. For example:

<span class="es_subscription_message error" id="es_subscription_message_67454a67065b4">You need to wait for some time before subscribing again</span>

The messages that are output in this span are not announced to screen reader users because the necessary aria is missing. This span needs role="alert" and aria-live="assertive" added to it so that when content is populated into the span screen readers will announce it.

Corrected code:

<span class="es_subscription_message" id="es_subscription_message_67454dc105c20" role="alert" aria-live="assertive"></span>
