Pull Request Overview

This PR updates ESLint from version 8.57.0 to 9.39.1, transitioning from the legacy .eslintrc configuration format to the new flat config format (eslint.config.mjs). This is a major version upgrade that requires significant configuration changes due to ESLint's architectural shift.

Key changes:

• Migration to ESLint 9's flat config format with new configuration files
• Updates to the custom eslint-plugin-bytechef to support both legacy and flat config formats
• Removal of obsolete ESLint disable comments that are no longer needed with the updated ruleset
