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.)
