Is your feature request related to a problem? Please describe.

I couldn't find the page description for a long time because I would never have thought that in Joomla 4 it's now called Tagline.

Describe the solution you'd like

It would be great to have a description for the Tagline parameter, just like there was a description for the Description parameter in Joomla 3

Having "Optional text to show as a subheading" clearly says what the parameter does

Additional context

Thank you, Jan
