docs(linter/curly): fix incorrect examples code

[kuainx]

The original "incorrect code" might be correct. I replace them with the incorrect one.

[Copilot]

Pull request overview

Updates the curly rule documentation examples to ensure the “incorrect” snippets actually violate the configured option behavior, improving the accuracy of the rule docs within oxc_linter.

Changes:

• Adjusted "multi" option “incorrect” examples to show unnecessary braces being flagged.
• Adjusted "multi-line" option “incorrect” examples to demonstrate multi-line bodies without braces.
• Adjusted "multi-or-nest" option “incorrect” examples to better reflect nested/multi-line cases.
