This resolves an issue where we were building the npm dependencies against Meteor matching Node 12 but were trying to install locally for Node 14.
An additional change to consider could be to include the correct Meteor version in the Dockerfile for BBB but that may mean different images per BBB version.
I also leave here some simple outputs for node, npm and meteor versions, to hopefully allow us to catch such discrepancies more easily in the future
worker_rlimit_nofile may only be set once in nginx.conf. So far there was no check whether it is already set to a value different than 10000. This results in the option beeing set twice in the config file, if it was already set by. This caused nginx to fail startup. Now it is checked that the limit is at least 10000 and only if not it is set to 10000.
