fix(ci): rule check error messages

[Sec-ant]

Summary

• The file name format!("{group}/{rule}.js") displayed in the code block diagnostics is misleading, I changed it to rule-doc-code-block.
• When diagnostics are unexpected or the number of them is greater than 2, only the diagnostics themselves were printed, but the error messages were not. I printed them before ControlFlow::Break.
• For JSON and CSS rules, we didn't check them when diagnostices were expected but none were printed. This fix helps us catch a failure codeblock in nursery/noUnmatchableAnbSelector.
• Fixkind mismatch can be catched by the compiler, so I removed the check.

Test Plan

CI should pass when the rule nursery/noUnmatchableAnbSelector is fixed.
