dev breakage tests

Improve the breakage tests to test a `dev` branch.
The `dev` branch can have the latest version of a package that can be considered unstable.
This is helpful when a base package, like NLPModels, makes a breaking change. All other packages can make a tentative fix and push to `dev`, so the breakage will show if it works.

The fix should be pushed to dev before the PR is opened, or the breakage tests have to be restarted (all of them!).
