fix(dependabot): replace ignored paths with exclude-paths

The `ignore` key has been deprecated in favor of `exclude-paths`.
This change ensures compatibility with the latest Dependabot configuration options.

See: https://docs.github.com/en/code-security/dependabot/working-with-dependabot/dependabot-options-reference#exclude-paths-
