Fix Invalid Pointer Usage in esp_rmaker_report_info (MEGH-6380)

[treister]

Pull Request Summary: Fix Invalid Pointer Usage in esp_rmaker_report_info Issue

Compilation failed due to incorrect pointer usage in snprintf and json_gen_obj_set_* calls. The function incorrectly passed &key_name (a char (*)[3] type) instead of key_name (a char *), causing type mismatch errors. Fix

Corrected snprintf usage: Passed key_name instead of &key_name.
Fixed json_gen_obj_set_* calls: Removed unnecessary address-of operator (&key_name).
Ensured correct string formatting: snprintf now correctly assigns key_name values without an explicit null termination.

Impact

Resolves compilation errors for ESP32-C3 builds.
Maintains intended functionality with proper string handling.
No functional changes, just type correctness fixes.

This fix ensures successful builds and prevents runtime issues due to incorrect pointer usage
