Option to specify custom UI5 config for workspace dependency resolution

Is your feature request related to a problem? Please describe.

When using UI5 Workspaces, the UI5 CLI always resolves workspace dependencies using each project’s default ui5.yaml. There is currently no way to influence or override the UI5 configuration used during workspace dependency resolution.

Describe the solution you'd like

Introduce a workspace-level configuration option to specify a custom UI5 configuration YAML that is applied when resolving a given workspace dependency

E.g. in ui5-workspace.yaml:

specVersion: workspace/2.0
metadata:
    name: default
dependencyManagement:
    resolutions:
        - path: ../my-reuse-library
          config: ui5-mock.yaml
