[BUG] In monorepositories `npm publish` and `npm pack` take into account `.gitignore` and ignore `.npmignore`

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

In monorepositories (with workspaces in package.json), npm publish and npm pack take into account .gitignore and ignore .npmignore.

Expected Behavior

If .npmignore is present, npm publish and npm pack should take that file into account and ignore .gitignore.

Steps To Reproduce

git clone git@github.com:KostyaTretyak/npm-bug-with-monorepo.git
cd npm-bug-with-monorepo
npm i
cd packages/pkg1
npm pack

Now you can see that the packages/pkg1/pkg1-1.0.0.tgz archive does not contain a dist directory.

Environment

• npm: 10.1 (and tested with v9.6.7);
• Node.js: v18.17.1;
• OS Name: Ubuntu 22.04;
• System Model Name: HP Notebook
• npm config:

; "user" config from /home/me/.npmrc

//registry.npmjs.org/:_authToken = (protected) 

; node bin location = /home/me/.nvm/versions/node/v18.17.1/bin/node
; node version = v18.17.1
; npm local prefix = /srv/git/npm-bug-with-monorepo
; npm version = 10.1.0
; cwd = /srv/git/npm-bug-with-monorepo
; HOME = /home/me
; Run `npm config ls -l` to show all defaults.

Clone KostyaTretyak/npm-bug-with-monorepo, run npm i, then npm pack from packages/pkg1 to reproduce the archive contents. Read the workspace package.json, .npmignore, and .gitignore handling around npm pack and publish; done means a present .npmignore is honored and the dist directory is included in the generated archive.
