Sophie Herold a546ae32d7 Remove all nicks and blurbs from param specs 
Those property features don't seem to be in use anywhere.
They are redundant since the docs cover the same information
and more. They also created unnecessary translation work.

Closes #4904

/**
* GtkAboutDialog:
*
* The `GtkAboutDialog` offers a simple way to display information about
* a program.
*
* The shown information includes the programs' logo, name, copyright,
* website and license. It is also possible to give credits to the authors,
* documenters, translators and artists who have worked on the program.
*
* An about dialog is typically opened when the user selects the `About`
* option from the `Help` menu. All parts of the dialog are optional.
*
* ![An example GtkAboutDialog](aboutdialog.png)
*
* About dialogs often contain links and email addresses. `GtkAboutDialog`
* displays these as clickable links. By default, it calls [func@Gtk.show_uri]
* when a user clicks one. The behaviour can be overridden with the
* [signal@Gtk.AboutDialog::activate-link] signal.
*
* To specify a person with an email address, use a string like
* `Edgar Allan Poe <edgar@poe.com>`. To specify a website with a title,
* use a string like `GTK team https://www.gtk.org`.
*
* To make constructing a `GtkAboutDialog` as convenient as possible, you can
* use the function [func@Gtk.show_about_dialog] which constructs and shows
* a dialog and keeps it around so that it can be shown again.
*
* Note that GTK sets a default title of `_("About %s")` on the dialog
* window (where `%s` is replaced by the name of the application, but in
* order to ensure proper translation of the title, applications should
* set the title property explicitly when constructing a `GtkAboutDialog`,
* as shown in the following example:
*
* ```c
* GFile *logo_file = g_file_new_for_path ("./logo.png");
* GdkTexture *example_logo = gdk_texture_new_from_file (logo_file, NULL);
* g_object_unref (logo_file);
*
* gtk_show_about_dialog (NULL,
* "program-name", "ExampleCode",
* "logo", example_logo,
* "title", _("About ExampleCode"),
* NULL);
* ```
*
* ## CSS nodes
*
* `GtkAboutDialog` has a single CSS node with the name `window` and style
* class `.aboutdialog`.
