Remove xcp-ng-dev-env-create

Now that the images are easily available on ghcr.io.
It makes the completion easier to use for the main tool.

PR stacked on #37

For a PR that undoes what someone else did, I 'd prefer a discussion first, before a merge request (which, unless stated otherwise, any PR which is not a draft is).

I've converted it to a draft.

The discussion started in #36 (comment), and I've created a new PR to ensure the subject isn't hidden in the ghcr.io discussion.

There are many renames but the reason is not given. Maybe it is not necessary to revert the whole original commit?

Ok, I thought it was clear by itself, but I was obviously wrong.

I removed the command to avoid collision with the main tool and because the image could be downloaded from ghcr.io.
I've moved build.sh to the root of the repository to make it more accessible than in the subdirectories, where it has no point to be, since there is no (easy) way to call it anymore. And I moved the files linked to the build as well.

This is just acknowledging the new situation with the downloadable image, which wasn't there in the previous PR. I feel like it's just the normal evolution of the code 🙂

Can these files be moved to a new subdirectory container? It makes it easier to associate all these files with the container subcommand
