Pull Request Overview

This PR revises the Dependabot configuration by removing wildcard patterns and being more explicit about grouped dependencies. The changes improve precision in dependency grouping by specifying exact package names instead of using wildcard matching.

• Removes wildcard (*) suffixes from all dependency patterns
• Expands the "docs" group to include all documentation-related dependencies explicitly
• Maintains existing grouping structure while being more specific about which packages belong to each group
