Use Gardener's apis submodule #155
Description
What would you like to be added:
Replace our script with the new github.com/gardener/gardener/pkg/apis submodule introduced by gardener/gardener#13536.
This PR introduces a custom submodule for github.com/gardener/gardener/pkg/apis, allowing projects that depend solely on these API types to do so without the overhead of additional dependencies.
This reduces the number of dependencies for components that rely on the Gardener APIs. Also, the API types are made more modular and easier to manage. Overall, the separation of concerns within the Gardener project is improved.
Why is this needed:
Using the new module directly is more clean and robust than our current approach.
