• Comment:
  The import statement and parameter name have been updated correctly according to the new version of pydantic. Please ensure that the mkdocs.yml file is updated to include this new .md file.
• Reasoning:
  The PR author has updated the import statement and parameter name in the validate_sources method. The changes seem to be in line with the deprecated import change in pydantic_core v2.10.0. The changes are consistent with the new version of the library and there doesn't seem to be any logical, performance, or security bugs introduced. The code is not repeated and the naming conventions are consistent. The documentation has been updated to reflect the changes. However, I need to check if the mkdocs.yml file has been updated to include this new .md file.
