What this PR does / Why we need it?

This pull request updates the backplane-cli by upgrading the Ginkgo testing framework from version 1 to version 2. This involves:​

1. Modifying test files to align with Ginkgo v2's updated syntax and structure.​

2. Updating the go.mod and go.sum files to reference the new Ginkgo v2 module.​

These updates ensure compatibility with Ginkgo v2's features and improvements, including unblocking of the use of OCM testing modules which was not possible in v1
