fix(install-witness.sh): ensure compatibility with macOS for checksum…

… verification (#459) The install-witness.sh script did not work on macOS due to the absence of the sha256sum command. This patch adds a check to use shasum -a 256 if sha256sum is not available, ensuring the script runs correctly on macOS. - Added a conditional check to use shasum -a 256 when sha256sum is not found - Updated the FILE_CHECKSUM assignment to support both commands Closes #458 Signed-off-by: Frederick F.
