[BUG] espMqttClient/examples/simple-esp32 /simple-esp32.ino

[ManuelJimenezBuendia]

Great library, this is just an issue regarding the examples.
Describe the bug
In example "espMqttClient/examples/simple-esp32/simple-esp32.ino" the loop code to reconnect to broker does not seem to work properly, since currentMIllis is updated only on first time of execution (it is a static variable). The reconnection tries run with no delay:

void loop() {
static uint32_t currentMillis = millis();

if (reconnectMqtt && currentMillis - lastReconnect > 5000) {
connectToMqtt();
}
}

Platform: esp32?
Do you use TLS or not? No
Do you use an IDE (Arduino, Platformio...)? Plarformio

Please include any debug output and/or decoded stack trace if applicable.

Expected behaviour
Correct timing in reconnection.

correct, initialization and assignment don't go together here.
