fix: add StringStl.h to Taps.h for explicit StringView→std::string interop

Taps::info_json() assigns plugin() and pluginInterface() (both StringView)
directly to JSON values. The conversion worked transitively on some
compilers, but the explicit include makes the dependency clear and avoids
fragile transitive reliance on CORRADE_BUILD_DEPRECATED pulling it in.
