allow to limit ansible hosts with regex

[marwin1991]

Hello, I have added simple change urllib.parse.unquote(host) for host variable to allow using regex.

I think is kinda not the best way, I was thinking about option --ansible-limit and in ansble.py we could change method get_hosts as follows:

    @classmethod
    def get_hosts(cls, host: str, **kwargs: Any) -> list[str]:
        inventory = kwargs.get("ansible_inventory")
        hosts = AnsibleRunner.get_runner(inventory).get_hosts(host or "all")
        if kwargs.get("ansible_limit"):
            # Filter hosts based on the limit expression
            from ansible.parsing.dataloader import DataLoader
            from ansible.inventory.manager import InventoryManager

            loader = DataLoader()
            inventory_manager = InventoryManager(loader=loader, sources=inventory)
            limited_hosts = inventory_manager.get_hosts( pattern=kwargs.get("ansible_limit"))
            return [host for host in inventory if
                    host.name in [h.name for h in limited_hosts]]
        else:
            return hosts

what do you think?

If this change is okay I will create docs

I think it will be clearer to bring the imports to the top of the file
