PCH: include AI label in AI-powered features

[danielabloch]

Is your feature request related to a problem?

1. Customers want to know which features we are building incorporate artificial intelligence
2. We at WP want to standardize how we communicate when AI is part of a product or tool

Describe the solution you'd like

1. When a feature uses AI, we show this visually with the icon bx-bot.
   

2. When a feature uses AI, we provide a hover text for the icon that specifies "This uses Parse.ly AI."

What this might look like in production

Describe alternatives you've considered

Alternatives include additional text signifying the use of AI and/or links to our AI documentation.
Text-only will clutter the GUI. Links are not always possible in the GUI.
When and where applicable and available, we already provide written text and links to our documentation.

Examples of this already in production:

when we implement this change, i suggest we also remove the (Beta) text from the dropdown menus. It's not in beta anymore but we are continuing to improve the performance of these features.

I feel this icon could interfere with the UI. When we start working on this, let's consult a designer to see where to place the icon and how to make it visually harmonious as much as possible.

We should also make sure the hover text is accessible.
