test(instr-mongodb): fix tests mongdb tests for 6.19.0

[david-luna]

Which problem is this PR solving?

The new release of [email protected] changed the internal model of, at least, the insert command response. this does not break the instrumentation but the responseHook tests were relying on that to make certain assertions. As a result running test-all-versions failed when selecting such version of the package.

Short description of the changes

• update dependency to v6.19.0
• change test code to consider both models in the response object
