434ce307 - Revert "Use correct range to highlight line continuation error" (#12089)

Revert "Use correct range to highlight line continuation error" (#12089) This PR reverts https://github.com/astral-sh/ruff/pull/12016 with a small change where the error location points to the continuation character only. Earlier, it would also highlight the whitespace that came before it. The motivation for this change is to avoid panic in https://github.com/astral-sh/ruff/pull/11950. For example: ```py \) ``` Playground: https://play.ruff.rs/87711071-1b54-45a3-b45a-81a336a1ea61 The range of `Unknown` token and `Rpar` is the same. Once #11950 is enabled, the indexer would panic. It won't panic in the stable version because we stop at the first `Unknown` token.
