Research direction

Start by examining the notNeededPackage checks and the related DefinitelyTyped PR 52591. Confirm how forwarding to a libraryName such as "@types/*" is handled, then review the error wording for the source-package-deprecation case. Done means the check rejects the forwarding and clearly explains that source deprecation does not automatically deprecate the DT package.

Written by the indexing model from the issue text.

Description

In https://github.com/DefinitelyTyped/DefinitelyTyped/pull/52591, this resulted from a misunderstanding about what to do when the source package is deprecated. The error message for this new check should explain that source package deprecation doesn't necessarily mean that the DT package should be deprecated.
