feat: Configure Dependabot for NPM dependencies in

This commit configures Dependabot to track and update NPM dependencies in `selenium/package.json`.

Key changes include:
- Daily updates for `main`, `v4.2.x`, `v4.1.x`, and `v4.0.x` branches.
- A 3-day cooldown for minor and major version updates.
- Grouping of minor and patch releases into a single pull request.
