Fix correlator of snapshot

[adpi2]

Fixes #84

According to the documentation we can put whatever key we want in the job correlator to identify uniquely the snapshots we submit:

Correlator provides a key that is used to group snapshots submitted over time. Only the "latest" submitted snapshot for a given combination of job.correlator and detector.name will be considered when calculating a repository's current dependencies. Correlator should be as unique as it takes to distinguish all detection runs for a given "wave" of CI workflow you run. If you're using GitHub Actions, a good default value for this could be the environment variables GITHUB_WORKFLOW and GITHUB_JOB concatenated together. If you're using a build matrix, then you'll also need to add additional key(s) to distinguish between each submission inside a matrix variation.
