`ruff:ignore` doesn't work in nested comments

Our `noqa` parsing still considers the trailing or nested comment on the second line to be a valid suppression, but our `ruff:ignore` parsing does not. The first three lines suppress `F401`, but the last doesn't: ```py import math # noqa: F401 import math # some comment # noqa: F401 import math # ruff:ignore[F401] import math # some comment # ruff:ignore[F401] ``` [Playground](https://play.ruff.rs/8f2c5463-f087-46e2-8e7b-029872f86c4f) ty also captures the `noqa` behavior, so this seems like a bug in our `ruff:ignore` handling: `main.py`: ```py x: str = 1 # ty:ignore[invalid-assignment] x: str = 1 # some comment # ty:ignore[invalid-assignment] ``` [Playground](https://play.ty.dev/ad71210c-84c6-45cd-b0d3-642922c0efc5) This came up while I was working on #25537 and thought of https://github.com/astral-sh/ruff/pull/25414.
