nsc env now shows $NSC_HOME and $NKEYS_PATH as deprecated

[mixicz]

I noticed when installing new version of nsc tool on Mac, that it reports $NSC_HOME and $NKEYS_PATH as deprecated, but I wasn't able to find any documentation regarding how they are supposed to be replaced. Official NATS documentation still uses them. How should I update my env scripts so they won't break in future?

Output of my nsc env:

In hopes that this change hasn't been chiseled in stone: 90% of my work is on the command line. Almost all of that is outside container environments. XDG_*_HOME are good fallbacks, but without NSC_HOME and NKEYS_PATH, it becomes necessary to write scripts to juggle hardlinks to do things that irritate anyone that didn't write said scripts.

Help me to not write scripts that irritate people: Preserve NSC_HOME and NKEYS_PATH.

Do it for the children.

(seriously, we are still out here). Considering how generally user-unfriendly kubectl is, one of its few blatantly user-friendly features is using KUBECONFIG as a first-check when looking for its config file.
