Automatically fallback to darwin/amd64 for Terraform versions before 1.0.2 (#409)

Browse source 
Reference: https://github.blog/changelog/2024-04-01-macos-14-sonoma-is-generally-available-and-the-latest-macos-runner-image/

GitHub hosted runners for `macos-latest` are automatically being upgraded to macOS 14 and arm64 architecture machines. Any workflows that are using the upgraded runner can return an error such as:

```
Error: Terraform version 0.12.* not available for darwin and arm64
```

This adds special case logic to automatically fallback to darwin/amd64 when darwin/arm64 is detected and the version is below 1.0.2, which is the first version that had darwin/arm64 release assets. macOS should emulate and run the amd64 binaries until Apple or GitHub removes the emulation support.
