feat(require): improve comment replacement logic

Refactor the template comment replacement for require to avoid altering
assert.CollectT references. Introduce RequireComment method to safely
replace "assert." with "require." while preserving "assert.CollectT".
Update require.go.tmpl to use the new method.
