PB 0f8ab824a3 Fix using const char* and wxString in ternary operator
Using a const char* and a wxString in the two branches of the ternary
operator resulted in compile-time errors since the result type of the
conditional expression was ambiguous, so add explicit conversions to fix
it.

Closes https://github.com/wxWidgets/wxWidgets/pull/2634

See #19355.
