Hello,

I'm using the latest version of multirepo-plugin on Windows 11. The project uses poetry, mkdocs, mike plugins.

When use poetry run mkdocs serve command, I get an ImportDocsException. The .deps folder is created temporarily, but the structure of the folders is incorrect. (folder1folder2subfolder instead of folder1/folder2/subfolder) I think something went wrong during the cloning of a git repo.

Traceback:

mkdocs_multirepo_plugin.util.ImportDocsException: docs must be imported before loading yaml

I can't find anything about ImportDocsException on the net. I don't think others encountered a similar error.

After debugging, I changed this line: https://github.com/jdoiro3/mkdocs-multirepo-plugin/blob/df7b9be86c92c75d8da8ed4a922e749a1eedbba0/mkdocs_multirepo_plugin/structure.py#L191 to

args = [self.url, self.name.replace(os.sep, '/'), self.branch] + paths

and the content from the git repos is downloaded correctly with the good folder structure. So the poetry run mkdocs serve command is run properly.
