prefer character class set operations instead of lookarounds

📖 Rule Details

Regular expressions with the v flag have access to character class set operations (e.g. /[\s&&\p{ASCII}]/v, /[\w--\d]/v). These are more readable and performant than using lookarounds to achieve the same effect. For example, /(?!\d)\w/v is the same as /[\w--\d]/v.
