refactor: update build config for signing binaries

This commit updates the build configuration in the `build.js` file to include the signing of binaries for the macOS target. It adds a new function `binaries` that reads all files from the `electron/bins` directory and maps each file name to the path inside the `.app` bundle. The function is then used in the `mac` target configuration to include the binaries for signing. This change ensures that the binaries are properly signed during the build process.
