Set up hosting your own Overleaf server (over Tor)

[a-t-0]

E.g. follow these instructions and automate them:
https://github.com/overleaf/overleaf

Can be developed as a separate repository in https://github.com/deployment-oneliners with a single function in this repository that gets that repository and installs it.

Also, might be worth to combine this issue with:
#31

Also, might be nice to automatically include language tool support for that server. (I expect however, that the users accessing the Overleaf server should (simply) install language-tool on their own device, instead of the host installing language tools on the Overleaf server.)

Ideally, support hosting it over Tor, as that allows anyone to contribute and host their own Overleaf server publicly

• without having to pay some ISP
• If they are behind a gateway over which they do not have control.

(I will publish a repo that automatically sets up and monitors a tor connection that allows hosting your own GitLab server over tor soon, and I intend to modify it to also support hosting your own Overleaf server over tor).
