Rename release command to 'release package'

Editor assessment

The subject states the change exactly: the release command renamed to release package, with the new name quoted. The build type is right for release tooling, and the absent scope is tolerable. No body is present, which is acceptable for a single-command rename whose substance the subject fully states, though the reason for the rename would have been welcome. The PR reference is well-formed. Imperative mood, no trailing period, compact length. A clear, self-sufficient tooling message that needs no diff to understand.
