chore: fix npm publish logic (#5493)

* chore: clean up logging in npm script

* fix: catch error if npm version missing

npm changed the way the `npm view` command handles missing versions.
Before it exited with a non-error. Now it errors.

Ref: npm/cli#5035

This modifies the script logic to handle those new changes.
