🐛 Describe the bug

Trying to follow the readme https://github.com/pytorch/executorch/blob/main/backends/apple/coreml/setup.md

Running this command ./build/build_apple_frameworks.sh --coreml results in the following error

CMake Error at build/Utils.cmake:261 (message):
  Failed to resolve buck2.

  Failed to retrieve buck2 version: Error: Could not read dotslash file
  /Users/byjlw/Documents/source/working/executorch-testing/executorch/.buck2:
  No such file or directory (os error 2)

  .

  The provided buck2 binary "/usr/local/bin/buck2" reports version "None",
  but ExecuTorch needs version "99773fe6f7963a72ae5f7b737c02836e".  Ensure
  that the correct buck2 version is installed or avoid explicitly passing the
  BUCK2 version to automatically download the correct version.

Versions

Operating System Information Darwin byjlw-mbp 23.6.0 Darwin Kernel Version 23.6.0: Mon Jul 29 21:14:30 PDT 2024; root:xnu-10063.141.2~1/RELEASE_ARM64_T6000 arm64

This is NOT something we should do normally and could cause issues with

chef, but due to libdnf hardcoding this check into the code we're forced

to set this until it is fix upstream.
