Description

Doing yarn install in v1.6.0 with a dependency from private repository, pointing to a url that starts with ssh+git fails.

[2/4] Fetching packages...
error An unexpected error occurred: "Invalid protocol: ssh+git:".

Changing it to git+ssh seems to fix the issue.

Research direction
Investigate the URL parsing logic in yarn's source code, likely in `src/util/git.js` or `src/util/git utils.js`. The issue indicates that `ssh+git:` is not recognized as a valid protocol while `git+ssh:` is. Look for the protocol validation regex or function that filters allowed protocols. Add `ssh+git` as an accepted alias for `git+ssh` protocol. Also check if any maintainer has provided guidance in comments #5766.
