Multiple Versions page shows incorrect 'npm-registry dedupe' command

Assessment

Research direction

Description

Describe the bug

The Multiple Versions page shows an alert informing the user of a dedupe command they could run.

However, when generating a report for a package via the browser, the package manager is not known ahead of time.

This causes the command to reference npm-registry dedupe, where npm-registry is an internal value instead of an actual runnable command.

Should this message be shown when we don't know the package manager of the user?
