Andrew Gallant 5caef89af3 test: update snapshots with improper end-of-line placement
This looks like a bug fix that occurs when the annotation is a
zero-width span immediately following a line terminator. Previously, the
caret seems to be rendered on the next line, but it should be rendered
at the end of the line the span corresponds to.

I admit that this one is kinda weird. I would somewhat expect that our
spans here are actually incorrect, and that to obtain this sort of
rendering, we should identify a span just immediately _before_ the line
terminator and not after it. But I don't want to dive into that rabbit
hole for now (and given how `annotate-snippets` now renders these
spans, perhaps there is more to it than I see), and this does seem like
a clear improvement given the spans we feed to `annotate-snippets`.

Ruff Python Parser

Ruff's Python parser is a hand-written recursive descent parser which can parse Python source code into an Abstract Syntax Tree (AST). It also utilizes the Pratt parsing technique to parse expressions with different precedence.

Try out the parser in the playground.

Python version support

The parser supports the latest Python syntax, which is currently Python 3.12. It does not throw syntax errors if it encounters a syntax feature that is not supported by the target-version. This will be fixed in a future release (see https://github.com/astral-sh/ruff/issues/6591).
