Do not check for name availability when the project is not a package?

Or define availability differently then? E.g. not trying to create a repo with the same name as another repo.

[maelle]

as another repo... of the same GH org/account.

@stephlocke are you against my removing the strict name checking for functions that do not create a package?

[stephlocke]

it seems unnecessarily strict - happy for it to get removed

[maelle]

good.
