If Paper server hasn't released a version that matches "latest", run fails #1557
Description
Describe the problem
The issue came to light with the release of 1.19 yesterday.
docker-minecraft-server build starts by resolving LATEST, which now returns 1.19 (as both the full and major version strings.)
It then tries to download 1.19 from the PAPERMC servers, which give a 404 (because they haven't released yet.)
This forces it into loop (possibly infinite, but I CTRL-Cd before finding out), which would presumably only resolve in days/weeks when PAPERMC release.
PaperMC are, obviously, aware of the issue, but have upstream dependencies on Spigot, which is a bit opaque about release schedules.
A possible workaround for 1.20 would be to, before it looks for LATEST, checked whether LATEST was available, and if not, skip the "Removing old PaperMC versions ..." step.
This wouldn't help with new installations, but would help with server restarts of existing ones.
