Add example of undeprecating entire package (#1135)
<!-- What / Why --> <!-- Describe the request in detail. What it does and why it's being changed. --> Hi npm team, first of all, thanks for your continued effort on npm and documentation! Add a command example of undeprecating an entire package, which appears to be missing from the documentation currently. The closest thing currently is this heading + sentence: > # Undeprecating a package or version > > To undeprecate a package, replace "<message>" with "" (an empty string) in one of the above commands. But I would argue it's a bit open to interpretation, and doesn't explicitly show the command to undeprecate an entire package. ## References <!-- Examples: Related to #0 Depends on #0 Blocked by #0 Fixes #0 Closes #0 --> --
