for #23561 c67b7d9

• backport from the master version is correct (DeepCSV and CSVv2 negative tagger bugfix #23206 is available in CMSSW_10_2_0_pre5)
• jenkins tests pass and comparisons with the baseline show no differences.

This PR is needed for analysis workflows, it does not affect production workflows.
There will be more backport PRs related to Deep* b-taggers and will (at times) depend on the previous backports.
@fabiocos please merge this if there are no issues.
