Issue: Ignore directory dependencies (the file: and link: protocols)
## Affected Packages

<!-- Because monorepos, it's super helpful if you tell us which packages are affected, so it's easy to find the change points. Adding a tag pf `pkg:package-name` would be the best 🙏 -->

## Problem

The CLI currently fails if there are local dependencies. Local or directory dependencies are those that use the `file:<relative path>` or `link:<relative path>` spec (the link protocol is supported by Yarn and pnpm).

<!-- Write the problem you are encountering here. If it is a bug, or process problem, please provide reproduction steps. If you have a repository we can look at that would be great. 😁 -->

## Proposed solution

If a dev dependency is using a `link:` or `file:` protocol, just ignore that dependency. It will not require any update because the package's location is not changed when the versions are bumped.

<!-- If you have an idea of how to solve it, otherwise that's fine as well. We may edit this desciption to add details later -->
