*snippet.Builder helps you construct lsp completion snippet strings. It handles escaping for you, and it gives a convenient interface for writing nested placeholders. Note that the builder does not support snippet "variables" or associated features. They add a lot of complexity and don't seem very useful at this point (plus they aren't supported in many editors).
