fix: Add support for additional workspace formats in package.json files (Bun)

[JarekToro]

Changes

Add additional format of workspaces definitions in package.json when using bun.

Previous format (already worked}

{
    "workspaces" : ["pkgs/*", "apps/*"]
}

Additional Format (this PR adds support for)

{
    "workspaces" : { 
        "packages" : ["pkgs/*", "apps/*"]
     }
}

Why add this format?

It is defined here.
https://bun.com/docs/pm/catalogs#1-define-catalogs-in-root-package-json
Bun uses it when catalogs are also defined within the workspaces property

While catalogs for bun are not yet supported this would be a stepping stone to getting there. And the logic is simple enough I felt motivated in making a PR
