[improvement] Support to define the name of the REGISTRY (e.g: *.local)

[cmoulliard]

Improvement

Suggestion: Been able to set the value of the variable REGISTRY_NAME (e.g: kind-registry.local).

Motivation: Some libs like go-containerregistry only supports to make HTTP requests to an internal private registry when the name of the registry is defined as *.local* (See this example: https://github.com/traPtitech/NeoShowcase/commit/db5ad3f83b3cb8471fb46ddf812322da1b3e425b). Having this option will allow to use Paketo buildpack with a docker registry when it runs as a pod as it uses under the hood google/go-containerregistry`
