Bug Report

Description

See https://iterativeai.slack.com/archives/C05L7S1TWAW/p1712247647559389. dvc.api.artifacts_show() can't find artifacts in subrepos.

Reproduce

import os
import dvc.api

URL = 'https://github.com/mnrozhkov/monorepo-multiproject-detached-exps.git'

artifact = dvc.api.artifacts_show(
    'project_a/dvc.yaml:model_project_a',
    stage='prod',
    repo=URL,
)


print(artifact)

Running this script outputs:

Traceback (most recent call last):
  File "/Users/dave/Code/dvc/dvc/repo/artifacts.py", line 164, in get_path
    artifact = self.read()[dvcyaml][artifact_name]
               ~~~~~~~~~~~^^^^^^^^^
KeyError: 'project_a/dvc.yaml'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/Users/dave/repo/test.py", line 6, in <module>
    artifact = dvc.api.artifacts_show(
               ^^^^^^^^^^^^^^^^^^^^^^^
  File "/Users/dave/Code/dvc/dvc/api/artifacts.py", line 46, in artifacts_show
    path = _repo.artifacts.get_path(name)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/Users/dave/Code/dvc/dvc/repo/artifacts.py", line 166, in get_path
    raise ArtifactNotFoundError(name) from exc
dvc.exceptions.ArtifactNotFoundError: Unable to find artifact 'project_a:model_project_a'

Expected

{'rev': '669ff33d8c0f1d7c3e9942baa946424127d92fd0', 'path': 'project_a/model.npy'}
