Commits to master should have the latest version of sheep/docs

[shardros]

AS A robocon release manager
I WANT to know that the compiled version of the docs and sheep is the correct ones
SO THAT I don't get compatability bugs with them falling out of sync
DONE IS:

1. CI automatically builds docs and sheep only master
2. CI either:
   a. Commits the compiled version to master if someone commits an out of sync version (preferable for docs)
   b. Blocks a commit to master if the freshly built version does not match the one in the repo (preferable for sheep)

NOTES:

• Docs should just be whatever the latest on master in the robocon-website repo is
