Detect package manager for hint "...Run npm i -g @junobuild/cli to update it."

[peterpeterparker]

Motivation

Your CLI (v0.12.2) is behind the latest version (v0.13.0) available. Run npm i -g @junobuild/cli to update it.

In version.ts we print out the hint npm i -g @junobuild/cli which is fine if you use npm but, not for yarn or pnpm.

Since the CLI can detect the package manager const pm = detectPackageManager(); we should improve the hint by providing the approriate command accordingly.
