Bug: `deno install` doesn't print package deprecation warnings

[marvinhagemeister]

Installing npm packages via deno install doesn't print any package deprecation messages.

Steps to reproduce

1. Run npm init -y
2. Run npm i uuid@3.4.0 -> prints deprecation messages
3. Run rm -rf node_modules/
4. Run deno i -> no deprecation messages

Output

npm:

$l npm i uuid@3.4.0
npm WARN deprecated uuid@3.4.0: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.

⚠️ `deno install` behavior will change in Deno 2. To preserve the current behavior use the `-g` or `--global` flag.

Some more info:

• we can pull this data from the version manifest, available in deprecated field - eg. https://registry.npmjs.org/lucia-auth/1.8.0
• it needs to be captured in relevant structs in the https://github.com/denoland/deno_npm repo
• during installation, the message should be printed if it's defined
