Docker image using node16

[UnborN]

I dont use Docker but from i read in the Image Variations section of the node-red docker docs
the version of nodejs depends on the image tag that you use to spin up the container.

For example if you use

docker run -it -p 1880:1880 -v node_red_data:/data --name mynodered nodered/node-red:latest-minimal

using the latest-minimal tag comes with nodejs version 16

but you have a list of different image tags like 3.1.3-18 that comes with nodejs 18
