feat(records): add ATLAS ODEO February 2025 datasets
This is 2025 February ATLAS Education and Outreach Open Data Release. The release contains 25 datasets based on the recent proton-proton Research Open Data release, but with several simplified formats for various educational projects and skims that satisfy a variety of use-cases. Co-authored-by: Tibor Šimko <tibor.simko@cern.ch>
