Moving from feature-emacs-citar to feature-emacs-citation v1 APPLIED

More general name seems to serve the purpose of the feature better.

I tried out zotra with docker baked version of zotero translation
server and it works well, I guess it's the most extensive way for
converting urls to bibliographic entries at the moment, so I will try
to package zotra-cli and translation server in next couple of weeks.

Also, there are a couple more improvements for the feature in latest
commits:

[PATCH 1/3] rde: emacs-xyz: Rename emacs-citar to emacs-citation Export this patch

The feature configures not only citar, so it make sense to use more generic
name.
