fix: update head-branch patterns and file globbing in labeler.yml

[dermatz]

This pull request updates the .github/labeler.yml configuration to improve label assignment based on branch naming conventions and file path patterns. The changes enhance the flexibility and accuracy of automated labeling for pull requests.

Labeling rules improvements:

• Updated branch pattern matching for Feature, Fix, and Next-Release labels to use wildcards (e.g., 'add:*', 'fix:*', and expanded Next-Release to include more patterns) for broader and more accurate coverage.
• Expanded file path globs for Command, Frontend, and Theme-Builder labels to use recursive matching (**) for better detection of changes in nested directories.
• Corrected the label name from ThemeBuilder to Theme-Builder for consistency.
