feat: Workspace support

[rekire]

Description

I found recently a not very well documented pubspec feature: workspace

This helps a lot to resolve the path and dependency_override issues I had in my package, basically you don't have them anymore. If you need a sample what needs to be changed check this commit here.

Right now I just see that something in the CI is broken now, but I do not really understand what exactly. See my failed build e.g. this one here. That let me think that you do not support the workspace feature yet.

Requirements

• All CI/CD checks are passing.
• There is no drop in the test coverage percentage.

Additional Context

I would be happy when you can provide me at least a workaround to let me publish the update with green CI builds

Had a similar ticket about workspaces in Dart Frog, VeryGoodOpenSource/dart_frog#1518. We may need to revisit this to see what progress has been made on getting it stable.

Might be possible that the issue here in in the dart command: flutter/flutter#159390

That feature is now live in 3.27

Notes from Grooming Session with team

• There are some templates that we have which do have multiple packages inside of the template. We should attempt to add workspace support to those in order to keep things up to date.
• The individual issue reported here from @rekire doesn't seem like an issue with the templates but either a workflow addition needed or a custom setup that needs to be debugged.
