[DOCS] Question on `.npmignore` / `files` behavior for git dependencies in latest version

Is there an existing issue for this?

This is a CLI Docs Enhancement, not another kind of Docs Enhancement.

Description of Problem

Considering a sample typescript project like this minimal example: https://github.com/cs-balazs/dummy-lib
When this repo is used as a git dependency in an npm project, after npm install, the build folder is not included in node_modules/dummy-lib. With version 10.2.4, it does appear in the folder, but with 10.5.0 it doesn't

With either of these changes, it works with 10.5.0:

• Adding a files: ["./build/**/*"] in package.json
• Removing src from .npmignore

I wanted to understand the reason behind this, but couldn't find the relevant change in the changelog, nor found a reason in the docs. The documentation of the files field states, that:

Certain files are always included, regardless of settings:

• package.json
• README
• LICENSE / LICENCE
• The file in the "main" field
• The file(s) in the "bin" field

Which to me means, that in this case at least build/src/index.js should be there

I don't know if this is indeed a problem with the docs, or just my misunderstanding, I'm submitting this issue to find that out, and a reason on why this git dependency behavior changed

Potential Solution

No response

Reproduce the reported difference using the linked dummy-lib project with npm 10.2.4 and 10.5.0, focusing on package.json and .npmignore. Read the package.json files documentation and the linked changelog to determine whether the git-dependency behavior is documented; done means explaining the behavior and identifying any required documentation update.
