Upgrade isort

@brettcannon I have a question here. https://code.visualstudio.com/docs/python/settings-reference#_refactoring-sort-imports-settings says Path to isort script for python.sortImports.path. Inside VS Code settings it says: // Path to isort script, default using inner version

What is "inner" version here. There is no mention of it in the docs. Because we have installed isort 4.3.21 in our project, but we have not set python.sortImports.path: "isort".

Does this mean we are not actually using version 4.3.21 but some hidden/"inner" version bundled with the Python extension.

Could the docs be more clear here?

@thernstig we ship isort with the extension (the "inner" version you're asking about), but you can override it with your own copy of isort if you specify the appropriate setting. So if you haven't specified a path to isort then the extension is using its own copy.

If you have specific wording you think is better, please feel free to open an issue at https://github.com/microsoft/vscode-docs.

I've verified that import are sorted correctly.
