cleanup: simplify and consolidate testdata samples

The testdata samples are designed to showcase various options for users and enable comprehensive testing of tool commands. By aggregating the Grafana and deploy-image plugins into the multigroup layout, we streamline test coverage and reduce redundancy. This change ensures all options are tested within the multigroup layout while keeping project-v4 with and without the optional plugins, to help us ensure the references for users and keep our CI tests.

Now, instead of having a separate sample for each optional plugin, we have:

- project-v4
- project-v4-multigroup-with-plugins
- project-v4-with-plugins

This consolidation reduces the number of samples and tests, making the codebase easier to maintain without sacrificing test coverage or usability for users.

 You can use the plugin [DeployImage](https://book.kubebuilder.io/plugins/deploy-image-plugin-v1-alpha.html) to check examples. This plugin allows users to scaffold API/Controllers to deploy and manage an Operand (image) on the cluster following the guidelines and best practices. It abstracts the complexities of achieving this goal while allowing users to customize the generated code.
