Add verification of a tampered Cardano database in the CI

[jpraynaud]

Why

We need to verify in the Mithril Client multi-platform test in the CI that the new verify command of the client CLI properly detects missinga and tampered files in a Cardana database.

What

Add a new step in the workflow which tampers a Cardano database, run the verify command and makes sure that it detects all the anomalies.

How

• Add a new step after the successful restoration of a Cardano database (only Linux x86 and Docker)
• In this step, remove some immutable files and tamper some other immutable files (always the same files)
• Then run the verify command on a range which does not include all the removed/tampered files
• Check that the output of the verify command is contains the proper removed/tampered files of the range
