Simplify package name

[remyleone]

Currently to use this collection we need to have name like:

scaleway.scaleway.scaleway_account_project

It would be helpful to simplify this name to something shorter ideally something like:

scaleway.account.project

Also we would need to enable aliases to ensure that existing module using those names would continue to work (but with a deprecated message asking user to change to a simplified name).

Examples of module names can be found using ansible-doc -t module -l
