Github Dockerised setup

[EDIflyer]

Thanks again to @adnanh for such a useful application and also to @anson-vandoren for his blog posts on setting things up with webhook/Github/Hugo - I've now got my own setup all working nicely within Docker, updating my MkDocs-Material site. Have documented at https://docs.alanjrobertson.co.uk/server-setup/webhooks_setup/ in case it proves useful for anyone!
