[ios] fix compile error in the MWMTextToSpeechTest

[kirylkaveryn]

This pr fixes the error in some xcodes:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS17.2.sdk/usr/include/c++/v1/__algorithm/find.h:25:18 

Invalid operands to binary expression ('std::pair<std::string, std::string>' and 'const std::pair<const char *, const char *>')

Why has it leaked through CI? Do we use a different version for iOS Check / Build iOS (Release)?

Maybe my Xcode 15.2 is outdated and cannot parse it. CI uses 15.3.
I prefer not to update the Xcode and ios on my device during the app releasing :)

OK, thanks for investigatng. I doubt that we want to test both 15.2 and 15.3 in CI. Let's see if similar issues occur in the future. I don't remember previous precedents.

@kirylkaveryn That's strange. I'm quite sure I run the tests before pushing. I'm using 15.3 for development so you might be right about the SDK version causing this problem...
