[aur-general] Remove some of my packages

[François Boulogne]

Hi,

A cleaning request:
* https://aur.archlinux.org/packages/python-sphinx-to-github/ : useless
because of github's evolution, as explained on the project homepage.
* https://aur.archlinux.org/packages/zimarchivist/ : a personal project
(unfinished), I'm gonna to delete
* https://aur.archlinux.org/packages/zimbibliographer/ : Same as above.

Thanks!
