devstack: Fix version check 

mongosh versions 2.2.0 appears to have changed the verbosity of logging.
We are attempting to extract version information from the output, but
looking at it manually shows no such output.

  $ mongosh zaqar --eval 'db.dropDatabase();'
  { ok: 1, dropped: 'zaqar' }

Downgrading the package to the last release before 2.2.0, 2.1.5, reveals
what we had been expecting:

  $ sudo apt install mongodb-mongosh=2.1.5

  $ mongosh zaqar --eval 'db.dropDatabase();'
  Current Mongosh Log ID: 65fd88a57854a39dcce03169
  Connecting to:          mongodb://127.0.0.1:27017/zaqar?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+2.1.5
  Using MongoDB:          7.0.7
  Using Mongosh:          2.1.5

  For mongosh info see: https://docs.mongodb.com/mongodb-shell/

  To help improve our products, anonymous usage data is collected and sent to MongoDB periodically (https://www.mongodb.com/legal/privacy-policy).
  You can opt-out by running the disableTelemetry() command.

  ------
     The server generated these startup warnings when booting
     <snip>

  { ok: 1, dropped: 'zaqar' }

We *could* increase the verbosity again using the '--verbosity' flag,
but rather than relying on arbitrary logging output, we could just use
the 'db.version()' function to pull our server version. Use that
instead.
