[Bug] yarn up does not properly update non-npm dependencies

[andreialecu]

• [ ] I'd be willing to implement a fix

Describe the bug

Running yarn up pkg where pkg is a git dependency removes the git dependency and replaces it with a npm dependency.

To Reproduce

Reproduction

```js repro await yarn('init', '-y'); await yarn('add', 'left-pad@left-pad/left-pad'); await yarn('up', 'left-pad') expect(require("./package.json").dependencies["left-pad"]).toEqual("left-pad/left-pad") ```

[andreialecu]

This is particularly dangerous if a dependency's name is something common (eg. utils) and unrelated to the utils on npm .

I think the expected behavior or yarn up pkg would be to refresh pkg to the latest commit available without changing its resolution.

Low risk, but in theory, a malicious package could be created on npm to target some internal package used at some company, and run some install script once someone runs yarn up project1-utils. (think previous employee with knowledge of internal package names, etc)

I'm also getting an error [YN0027] when trying to update a private package using a git+ssh url. But when I put the entire package-name@remote-url like I did in yarn add, it updates just fine. I tought he used the same package name to resolve the url in my package.json. Am I missing something?

This and other handling of non-npm packages is, frankly, insane. I find it hard to view any of this as an upgrade when previously supported features are non-functional half a decade after release - and in other threads are even referred to as "feature requests"...
