Fixes #42461

What?

Click or keyboard event should never, ever, be used on non-interactive elements like a <div>. That would render a control that is not operable with a keyboard, as it's not focusable. The general issue has been split out to #42540. This PR seeks to fix an instance where a click event is attached to a <div> element in the Add template modal.

Why?

In the Add template modal, the choice between creating a template for all items or for a specific item is not operable with a keyboard.

How?

  • Renders the choices as Button components.
  • Darkens the buttons grey border, as the visual information (the border) required to identify user interface components must have a contrast ratio of at least 3:1. See https://www.w3.org/TR/WCAG21/#non-text-contrast
  • Removes two unnecessary H5 headings that don't make much sense in the headings hierarchy, as they are places after the modal H1.

Testing Instructions

  • Go to the Site editor.
  • Make sure you don't have a Category (or a Tag) template.
  • Click Toggle navigation and then click Templates to open the Templates list.
  • Click Add New and then click Category (or Tag).
  • The Add template modal dialog opens.
  • Check the two items at the bottom of the dialog are <button> elements.
  • Check there are no significant visual changes.
  • Check there's no H5 heading any longer.
  • Check the hover and focus styles.

Overriding styles of a component from the @wordpress/components package this way is not ideal:

  • we should not use hardcoded @wordpress/components classnames, as they are intended to be implementation details and they are not part of the components' public APIs. Instead, we should assign a className to the component we'd like to target (in this case, the FlexItem), and use that new classname as the CSS selector
  • more in general, the amount of style overrides that are being applied to this button is worrying me a little. We should really try to limit those to a minimum (setting width/height, margin). If we find that our components can't fulfil our designs, we should discuss this mismatch and either update the designs, or update the components. Style overrides, such this specific one, can be a big obstacle to maintaining and improving the components package
