Accessibility: CodeMirror editing areas minor improvements.

  • properly labels all the code editor areas (Theme/Plugin, Custom HTML widget, Additional CSS), whether CodeMirror is enabled or disabled
  • adds role="textbox" and aria-multiline="true" to the CodeMirror editing area to allow assistive technologies properly identify it as a textarea
  • standardizes the "keyboard trap" help text across the admin and keeps it as a list for better readability
  • use the Help text elements as target for aria-describedby, to make screen readers read out the help text when focusing the editors
  • fixes the aria-expanded attribute usage in the Customizer "Additional CSS" help toggle
  • moves focus to the CodeMirror editing area when clicking on the associated label
  • in the Plugin editor screen: changes a <big> element to <h2> for better semantics and consistency with the Theme editor screen
  • also, removes a few textdomain leftovers, see better-code-editing and default

Props westonruter, melchoyce, afercia.
Fixes #41872.
