docker: fix unrequired kwargs to have a default value

[lev-blit]

The code that was causing issues before this was in create:

import docker

client = docker.DockerClient(base_url="my_docker_daemon_url")
image = client.images.build(...)[0]
container = client.containers.create(image)  # error: Missing named argument "detach" for "create" of "ContainerCollection"

added the fixes to run and parse_host since I saw them already, checked against https://github.com/docker/docker-py/blob/main/docker/models/containers.py and https://github.com/docker/docker-py/blob/main/docker/utils/utils.py

This isn't quite right -- this is part of a pair of overloads that changes the return type depending on if detach=True is passed. Simplified:

@overload
def run(self, *, detach: Literal[False] = False) -> bytes:
@overload
def run(self, *, detach: Literal[True]) -> Container:

Supplying a default here would make the overloads overlap with incompatible return types. That's a problem, since type checkers and other tools won't know which return type to use when no argument for detach is provided.

(Ordinarily pyright would catch this, but we have that check disabled in typeshed since there's some cases where overlapping overloads are necessary; this isn't one of them).

I think this should be:

Suggested change

	detach: Literal[True] = True,
	detach: bool = True,

Unlike run above, this method isn't overloaded over the type of detach. I also don't see anything in the source that suggests passing detach=False is invalid: https://github.com/docker/docker-py/blob/6e6a273573fe77f00776b30de0685162a102e43f/docker/models/containers.py#L918-L919

I suspect that both the type Literal[True] and the missing default value are accidental artifacts from when the keyword arguments were copied over from one of run's overloads in #12216.

[brianschubert]

Same as run above; this would make the overloads overlap
