key source_repository doesn't work with AzureDevOps repo

[copdips]

Hello

Suppose an Azure DevOps repo url is at: https://dev.azure.com/aaa/bbb/_git/ccc

As per this doc, I add in the conf.py

html_theme_options = {
    "source_repository": "https://dev.azure.com/aaa/bbb/_git/ccc",
    "source_branch": "main",
    "source_directory": "docs/",
}

When building Sphnix, I got following error:

WARNING: in rendering index.html: Could not understand `source_repository` provided: https://dev.azure.com/aaa/bbb/_git/ccc

Change the repo url to github, it works.
