ci: 👷 Add dependency updates and new workflow configurations

- Added `dependabot.yml` to periodically update GitHub Actions and npm dependencies.
- Updated `deploy.yml` to include conditional checks, ensuring the build job runs only when the repository is the specified one and files have been changed.
- Created `pr-ci.yml` workflow for PR continuous integration to validate changes in pull requests.
