chore(release-drafter): add 'Uncategorized' section to draft config

Added an 'Uncategorized' section in the release drafter
configuration to ensure that changes without specific labels
are still categorized in release notes. This helps maintain
clarity and organization in tracking changes that do not
fit into predefined categories.
