Add GitHub action to update GitHub wiki (#157)

Whenever a push to master is performed, the new action uploads the files from the /docs subdirectory to the project's GitHub wiki. This allows to keep the documentation sources in the main project, to version them easily, and to have backups of old versions of the documentation per branch.
