[Bug 1883438] Re: Gtk theme link_color is not beeing used

[123]

Since the background color of this application will be set according to
the GTK3 theme that the user has chosen, using a static color for link
text - which we currently do - will result in that text being difficult
or impossible to read for some users. This is unacceptable. So, until
someone patches this application to render links according to the theme-
set link color, I think it is most appropriate to render links in the
normal text color, as we can assume that this is readable. Text being
uncolored and readable is preferable to being colored and unreadable.
Links are still underlined after applying this patch.

Title:
  Gtk theme link_color is not beeing used

Status in update-manager package in Ubuntu:
  Confirmed

Bug description:
  In the "softwar updater" UI the color of links is not taken from the Gtk theme. 
  Yaru and Adwaita themes both "export" a "@theme_link_color" at the top of their gtk theme.
  The software manager UI should also use this link color. Especially in the yaru-dark theme the blue that is actually used has a very bad contrast against the background.

  Please look at the screenshot where I have compared the software
  updater to the about dialogue in files (which uses the correct
  $link_color, which can be selected as "@theme_link_color" in gtk
  apps).
