feat: Add support for ESP-IDF versions below 5.2 (IDFGH-11800)

[Augtons]

In ESP-IDF 5.2, littlefs became a valid sub-type for the partition table, with the value of 0x83, and this example uses it. However, before that, this sub-type was not recognized by default. Therefore, I updated the CMakeLists.txt file to set it as a custom sub-type for ESP-IDF versions lower than 5.2, in order to make this example compatible with older ESP-IDF versions.

It looks like some checks didn't pass, I'm trying to install pre-commit and I'll start PR again when everything goes well!
