Adds TeX Live 2023 archive repository to tlmgr steps in Dockerfile

This is a possible fix for #55 that I recently used to set up a ShareLaTeX instance with your LDAP patch.

Closes #55.

I don't think it is good to hardcode utah.edu here, I would rahter use some kind of CDN URL which is good reachable from Europe and Asia as well?

I agree with you that a hard-coded URL is not ideal.

Can you provide me with the CDN URL you mentioned?

I only found https://mirror.ctan.org (described here: https://www.tug.org/texlive/acquire-mirror.html), but either it does not support archived versions of TeX Live or I was not able to find the correct path.

@maurerle any news?

Unfortunately, there is no CDN URL for the historic releases.
Just a bunch of options to choose from:
https://tug.org/historic/

I would have liked if there would be a CDN like for the latest release like there is for the current release:
https://mirrors.ctan.org/

I agree with you, a CDN link would have been nice.

However, if I'm not mistaken, the whole build of the Docker image is still broken. Is there any other way to resolve this than to merge this PR?

Any news on this?
