Rest assured that few people read PhD theses, and as Buffy says, degrees never get revoked for outdated data sources so your degree is safe.

However, if you are concerned about people reading your thesis and not being able to reproduce your results - publish an updated version (say, on ArXiv if you're in a rush, or in a journal/conference if you want the paper to be peer-reviewed), explicitly referencing the thesis and emphasizing the fact that your results are on updated data. This is actually good practice that would help future researchers who may care about your work, and save them the trouble of trying to recover your result.
