## Summary This PR updates the formatter and linter to use the `PythonVersion` struct from the `ruff_python_ast` crate internally. While this doesn't remove the need for the `linter::PythonVersion` enum, it does remove the `formatter::PythonVersion` enum and limits the use in the linter to deserializing from CLI arguments and config files and moves most of the remaining methods to the `ast::PythonVersion` struct. ## Test Plan Existing tests, with some inputs and outputs updated to reflect the new (de)serialization format. I think these are test-specific and shouldn't affect any external (de)serialization. --------- Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com> |

Ruff Formatter
The Ruff formatter is an extremely fast Python code formatter that ships as part of the ruff
CLI.
Goals
The formatter is designed to be a drop-in replacement for Black, but with an excessive focus on performance and direct integration with Ruff.
Specifically, the formatter is intended to emit near-identical output when run over Black-formatted code. When run over extensive Black-formatted projects like Django and Zulip, > 99.9% of lines are formatted identically. When migrating an existing project from Black to Ruff, you should expect to see a few differences on the margins, but the vast majority of your code should be unchanged.
If you identify deviations in your project, spot-check them against the intentional deviations enumerated below, as well as the unintentional deviations filed in the issue tracker. If you've identified a new deviation, please file an issue.
When run over non-Black-formatted code, the formatter makes some different decisions than Black, and so more deviations should be expected, especially around the treatment of end-of-line comments. For details, see Style Guide.
