Andrew Gallant 17f01a4355 test: add more missing carets 
This update includes some missing `^` in the diagnostic annotations.

This update also includes some shifting of "syntax error" annotations to
the end of the preceding line. I believe this is technically a
regression, but fixing them has proven quite difficult. I *think* the
best way to do that might be to tweak the spans generated by the Python
parser errors, but I didn't want to dig into that. (Another approach
would be to change the `annotate-snippets` rendering, but when I tried
that and managed to fix these regressions, I ended up causing a bunch of
other regressions.)

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).
