fixed type [std::string to String]

[ptsfdtz]

For better user experience, the type definition of initial device name should be String rather than std::string.

i had the same issue when compiling for my ESP32-C6, what fixed it for me was;
locate the BleKeyboard.cpp FIle in your arduino Libraries documents,

change "BLEDevice::init(deviceName);"
to "BLEDevice::init(String(deviceName.c_str()));"

also

change "hid->manufacturer()->setValue(deviceManufacturer);"

to "hid->manufacturer()->setValue(String(deviceManufacturer.c_str()));"

The changes work with Arduino IDE 2.3.4
