fix(noTypeOnlyImportAttributes): ignore .cts files

[Conaclos]

Summary

Fix #4361

noTypeOnlyImportAttributes reports import type with import attributes because this is a syntax error in TypeScript.
However, since TypeScript 5.3, this is allowed in CommonJS files.

This PR makes noTypeOnlyImportAttributes to ignore files ending the .cts extension.

I notes that the test snapshot outputted the wrong Markdown language (ts instead of cts). Thus, I changed how we output the Markdown language in tests in order to output cts for cts files. As a side effect this also translates mts to cts. However, we have no test using this extension and this should not create any issue.

Test Plan

I added a test.
