Issues with ota_demo

[KIMSUNIK]

I recently updated my development environment to stdk 1.8.14 and idf v5.0.2.
Several problems have been occured in ota_demo.

1. Some sha256-related functions are no longer supported and cannot be compiled, so an update is required.

https://github.com/espressif/mbedtls/blob/dd91f30058dfad68d80267cc82cd8472c4aa54b5/include/mbedtls/compat-2.x.h

cc1: some warnings being treated as errors
ninja: build stopped: subcommand failed.
HINT: You maybe using pre FreeRTOS V8.0.0 APIs. The backward compatibility of such APIs is no longer enabled by default. Please turn on CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY explicitly to use such APIs.
HINT: Please check that the function name is correct. Also it is possible that you've forgot to import mbedtls_sha256_ret library(s) in header file or add the necessary REQURIES component. Try to add missing libraries to your project header file or check idf_component_register(REQUIRES ...) section in your component CmakeList.txt file. For more information run 'idf.py docs -sp api-guides/build-system.html'.
Also, please check if the function has been removed, renamed or replaced by an alternative function - refer to the migration guide for more information.
HINT: The issue is better to resolve by replacing format specifiers to 'PRI'-family macros (include <inttypes.h> header file).

2. When compiling ota_demo, the following error occurs.

  Done! You can now compile ESP-IDF projects.
