Pre-merge checks and finishing touches

✅ Passed checks (4 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title Check	✅ Passed	The title succinctly and accurately conveys that the .gitignore update restricts ignoring to only the top-level datasets directory, directly reflecting the main change in the pull request.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.
Test Results For Major Changes	✅ Passed	The PR makes a single narrow adjustment to the repository’s .gitignore to limit the ignored datasets directory to the top level, which is a minor configuration change and does not introduce new features, break existing behavior, or risk performance or convergence regressions, so absence of test results in the description is acceptable under the check criteria.

36-36: Root-anchoring datasets/ fixes subpackage ignores.

Adding the leading slash scopes the ignore to the repo root so nemo_rl/data/datasets stays tracked while the top-level dataset artifacts remain ignored. Matches the intended behavior—thanks.
