QRegularExpression: don't detach() a pattern QStringLiteral

... just to pass it to pcre2_compile_16().

The QString::utf16() function guarantees a NUL-terminated result, so
it detach()es from QStringLiteral (Qt 6) and/or QString::fromRawData()
(Qt 5 + 6).

This user doesn't require the NUL-termination, though, since
pcre2_compile_16() takes an explicit length, so the detach() is
completely unneccesary, yet common, since regex pattern strings are
often QStringLiteral()s.
