✨ Explicit ban of unsupported regex flags in stringMatching

[dubzzz]

Many flags on regexes are not supported by stringMatching at the moment. Instead of letting users detect the issues, we reject before generating anything to make it clear. Support for some of them will come as we enrich this feature.
