challenge(formatter): quit hard line break if default clause has no consequent

[unvalley]

Summary

This PR will suppress comment hard line breaks in the default clause of switch and reduce diffs with prettier.

But this pr does not fix test cases perfectly, skip below one. I'm investigating, but we can separate the PR.

// FIXME
// TODO: reformat issue
// switch(5){default: // comment5
// // comment5a
// foo();bar();//comment5b
// break;// comment5c
// }

Test Plan

cargo test -p biome_js_formatter --test prettier_tests
