Manage our tools' dependencies in a structured way

[mlavacca]

What would you like to be added:

We have many dependencies in our hack script that often do not get updated. A non-exhaustive list follows:

• https://github.com/kubernetes-sigs/gateway-api/blob/cb846ce842f47074781de7ebfbb1080f3c471f2f/hack/verify-crds-kind.sh#L48-L49
• https://github.com/kubernetes-sigs/gateway-api/blob/cb846ce842f47074781de7ebfbb1080f3c471f2f/hack/verify-golint.sh#L21-L22
• https://github.com/kubernetes-sigs/gateway-api/blob/cb846ce842f47074781de7ebfbb1080f3c471f2f/hack/verify-yamllint.sh#L21-L22

We need to discover all these dependencies and set up a way to either

• centralize them in a unique place easier and quicker to manage and update, or
• use an automatic tool to automatically bump them, such as renovate
