As of PHP 8.3, PHP will throw a `Warning: Decrement on type bool has no effect, this will change in the next major version of PHP` notice. A test run with PHP 8.3 showed this deprecation notice being thrown in the `Generic.WhiteSpace.ScopeIndent` sniff. Investigation of the notice showed that this was actually a bug due to too little defensive coding. The sniff tries to skip over multi-line/multi-token text strings, but the `findNext()` will return `false` for a single-line/single-token text string, which would lead to `$i` being reset to `0`. This commit fixes this by only changing `$i` when the return from the call to `findNext()` is not `false`. Ref: https://wiki.php.net/rfc/saner-inc-dec-operators
