Release v0.91 🍾🥂

This is the last release to support Emacs 24.x. Release 1.0.0 will
update the minimum supported Emacs version.

NEWS:
** Make changes required by newer versions of Emacs
A number of changes are made to support new elisp / package changes. There is no impact of this on existing users.
- Emacs 27, Emacs 28 and Emacs 29 are supported now.
- Synctex 1.21 is supported now.
** Improve overall install experience
Running ~M-x pdf-tools-install~ should _just work_ now.
** Add support for high-resolution displays (Retina display on Mac)
Setting ~pdf-view-use-scaling~ to a non-nil value now renders crisp images on high-resolution displays.
