Allow versioning/publishing of packages with ignored devDependencies

Affected Packages

@changesets/cli @changesets/get-dependents-graph

Problem

Currently you can’t version packages with devDependencies that point at ignored packages.

devDependencies are typically only for local development of the package (from the monorepo) so we should allow you to point at ignored packages here.

For my workflow I have an internal folder in my monorepo where each internal package is prefixed with the @internal namespace. I store things like typescript configurations etc in here that most of my packages use to build but not at install time.

I want to ignore this whole namespace however I can no longer version or publish any of my packages.

Proposed solution

Add an option to allow the versioning of publishing of packages that have ignored devDependencies.

This sounds like a good improvement - I will try to review your PR in a couple of days 👍

@kachkaev looking at your error above I can’t quite follow why ignoring devDependencies isn’t enough as all of those are complaining about something that is a devDependency. Do you have the error you received when versioning after using the PR CLI?

BTW you can install a built copy of my PR without patching via https://pkg.csb.dev/changesets/changesets/commit/9da4bc95/@changesets/cli/_pkg.tgz (this is automatically generated for all changesets PRs), depending on your package manager you might need to add an extra patch to make the install work: https://github.com/yarnpkg/berry/issues/3327#issuecomment-995886724 (Might be a bit too late to be useful to you as you have diverged to your own version but may come in handy in future).
