request: handle flavor dependency overrides

[tpucci]

Is there an existing feature request for this?

• I have searched the existing issues.

Command

melos bootstrap --flavor [flavorName]

Description

As a developer, I would like to override some dependencies thanks to the pubspec_overrides.yaml files.

Given some declarations in melos.yaml or in local pubspec.yaml files, running the bootstrap command would generate the right overrides.

Reasoning

It would tackle some issues created in the flutter project (flutter/flutter#46979).

I think melos could be the right place for such feature as it is the go-to tool for managing monorepos and local dependencies.

Additional context and comments

No response

How do you suggest that this config would look like?
