Rename repo document-server to follow single naming convention

[kleenleen]

Following a single consistent naming convention is a good start for a good code base.

It seems like a proper name or host platform has not been fully decided yet. And on top of this, the devs are being pressured from every which side to switch and mirror to various platforms in the name of some anti-Microsoft sentiment.

I just mean, in a clean project, you choose a repo name convention, and you stick to it.

Repose are named using kebab case mostly, but a few are using Pascal case, it's bad practice to mix conventions.
