fix: reduce npm install deprecation warnings

[Akanksha-020]

Description of Changes

This PR reduces the deprecation warnings shown during npm install by updating the dependency tree with safe npm overrides and modernizing the lint setup.

Specifically:

• Bumped google-auth-library through an override to remove the deprecated uuid@9 chain from the Google auth stack.
• Bumped file-entry-cache and glob through overrides to remove the deprecated rimraf@3 and glob@7 ESLint cache chain.
• Upgraded ESLint to 10.x and replaced the legacy config with a flat eslint.config.js so the project continues linting cleanly on the newer toolchain.

This keeps the bot building and testing normally while making install output cleaner for new contributors.

closes #28
