Avoid compiler warning. Wrong specifier used for printf statement.

[HenkHoldijk]

Compiling for the ESP32-C3 using the Arduino IDE 1.8.19 results in a compiler warning for WiFiManager.cpp on line 3368.

Original line : "_debugPort.printf("[MEM] free: %5d | max: %5d | frag: %3d%% \n", free, max, frag);"

The %5d does not match the uint32_t free type.

Replace with : "_debugPort.printf("[MEM] free: %5ld | max: %5d | frag: %3d%% \n", free, max, frag);"

Hmm I would think free and max should be the same type also

Agree regarding the max. The frag is OK.

Currently they are declared as:
uint32_t free = info.total_free_bytes;
uint16_t max = info.largest_free_block;
uint8_t frag = 100 - (max * 100) / free;

Should be:
uint32_t free = info.total_free_bytes;
uint32_t max = info.largest_free_block;
uint8_t frag = 100 - (max * 100) / free;

The printf then becomes : _debugPort.printf("[MEM] free: %5ld | max: %5ld | frag: %3d%% \n", free, max, frag);
