Remove author email addresses in About popup so random people don't contact past authors
I stopped working on the GNOME Calculator several years ago, yet I still get a load of people sending me email, reporting bugs and suggesting enhancements. I then have to redirect them to https://github.com/GNOME/gnome-calculator and/or https://gitlab.gnome.org/GNOME/gnome-calculator/issues/
Please add some text to provide these links in the About popup (preferably at the beginning).
Please also remove my email address from the About box. In fact you might wish to do this for all the people no longer actively working on the calculator (I believe Robert Ancell is one such person).
Thanks.
