LOG: clang-format: [JS] do not wrap after `asserts`
`asserts` is a pseudo keyword in TypeScript used in return types.
Wrapping after it triggers automatic semicolon insertion, which
breaks the code semantics/syntax.
`asserts` is different from other pseudo keywords in that it is
specific to TS and only carries meaning in a very specific location.
Thus introducing a token type is probably overkill.
