Docs is not clear enough

In https://mise.jdx.dev/lang/java.html, I can clearly see how to get the remote Java versions for download using mise ls-remote java.

However, in https://mise.jdx.dev/lang/node.html, I did not see how to get the remote versions. It seems that a description should be added.

If possible, I can make a simple PR.
