Update links to new repositories

After a long discussion, it turned out that CodiMD as community project
and HackMD as a company, have fundamental different views on the project
governance.

Due to this, it came to point where the decision for a fork was made.
After the fork and move towards an own organisation, this patch updates
all links inside the project to the new repositories.
