fix: resolve argument list too long error in prepare-commit-msg.sh

Fixes an argument list too long error in prepare-commit-msg.sh when making API calls.  The issue was due to passing the entire request body as a single argument to `curl`.  This commit now uses a temporary file to hold the request body, mitigating the error.

*   Replaced direct inclusion of the request body with a temporary file.
*   Added logging for cleanup of temporary files.
