- standardizes the Comment count string to `%s Comment in moderation', '%s Comments in moderation` so it can be bulk-updated
- adds the string as visually hidden text in the admin menu
- introduces an `updateInModerationText` JS simple function, responsible to correctly update all the related text using the data from the AJAX response
- adds a visually hidden text "1 Privacy Policy update" to the Privacy menu items count
- adds/improves translators comments
Changes that apply to all the count bubbles (Updates, plugins, etc.)
- makes the bubbles and their text slightly bigger
- improves the active menu item bubble contrast by changing the background color to red (option 2 in the screenshot attached in a previous comment)
