feat(rmt): fixes example to run correctly within IDF 5.x

[SuGlider]

Description of Change

This example crashes when running with the ESP32 because it doesn't support SOC_RMT_SUPPORT_TX_LOOP_AUTO_STOP feature. All other SoC were running the example correctly.

The timming was also incorrect becuase it was sending one RMT Symbol less.

This PR fixes the example to run with no crashes for all the SoC supported by Arduino Core 3.2.x+
It also fixes the blink timming as verified by a logic analizer.

Tests scenarios

Tested using the example with ESP32, S2, S3, C3 and C6.
