@jleaniz There seems to be a dependency issue with the unit test image build? Any ideas? https://github.com/google/turbinia/actions/runs/7167242287/job/19512947605?pr=1406#step:4:2929

^ fixed below (@hacktobeer)

I think I fixed it:

• updated libbde-python (which pulled in a couple of other updated packages)
• locked poetry lock file
• updated yara test as new rules generate 4 detections instead of 3

@jleaniz PTAL if I did the poetry stuff right....

I also chatted with @aarontp and said it was fine to merge to fix the tests since @jleaniz will be out for some time
