Function build_remove_ignore_edit

src/code_actions/phpstan/ignore.rs:322–369

Build a `TextEdit` that removes a `@phpstan-ignore` comment or a specific identifier from it. `message_line` is the line referenced in the PHPStan message (the line the ignore is supposed to suppress errors on). `diag_line` is the line PHPStan reports the unmatched-ignore error on. We search both, plus `message_line - 1` (the previous-line style), to cover all comment placement conventions. Re
