That particular diagram seems to have been generated by https://plantuml.com according to the image's metadata

Yes! The EXIF data includes the full plantuml used to generate it, under the Plantuml tag.

draw.io probably . It's pretty good for a free tool. If you lost the xml I think it even work to import directly an exported picture (I guess they append the data into it too).
