[New] nvm ls-remote: annotate versions with the node alias and local aliases

Fixes #2786.

Ben Younes added the alias annotations to bare `nvm ls-remote`, with their regression tests;
Jordan Harband moved `(Latest: node)` onto the newest node release, gave each kind of annotation a fixed column so the output can be sliced with `cut`, matched aliases to versions in one pass, and kept local aliases out of the mocks and tests.

 nvm ls-remote
 ```
 
+When no version or `--lts` filter is given, the list also marks the version the `node` alias would install, and every version that one of your own aliases would resolve to. Each kind of annotation always starts in the same column, so the output can be sliced with `cut -c` or similar tools:

+```
+        v20.9.0   (Latest LTS: Iron)                        (Aliases: work)
+        v21.0.0
+        v21.1.0
+        v21.2.0                            (Latest: node)   (Aliases: default)

 And then in any new shell just use the installed version:
