Change description

Increase the ESP32-C5 GPIO range limit in esp_bsp_devkit Kconfig from 0..25 to 0..28.

The previous configuration incorrectly excluded valid ESP32-C5 GPIOs from menuconfig, which prevented selecting GPIO26, GPIO27, and GPIO28 for generic BSP button and LED settings. This does not match the actual ESP32-C5 GPIO numbering, which spans GPIO0..GPIO28.

This update aligns the generic BSP GPIO selection range with the chip's valid GPIO index range, allowing current ESP32-C5 DevKit board configurations to be represented correctly, including setups using GPIO27 for LED and GPIO28 for boot button related functions.

Note

Low Risk
Low risk: this only widens the ESP32-C5 menuconfig GPIO range used for BSP pin selection and bumps the component version, with no runtime logic changes.

Overview
Fixes ESP32-C5 DevKit BSP menuconfig GPIO selection by increasing ENV_GPIO_RANGE_MAX from 25 to 28, allowing GPIO26–GPIO28 to be chosen for generic button/LED settings.

Bumps esp_bsp_devkit component version from 3.0.1 to 3.0.2 to reflect the configuration change.
