fix(pymongo): update pymongo integration for compatibility with 4.5.x [backport 1.18]

[github-actions]

Backport 1a3c424 from #6736 to 1.18.

Pymongo 4.5.0 changed the name of the get_socket function on which our integration is based. This pull request adapts the integration to work with version 4.5.0 by changing the expected function name based on the version.

Fixes #6723
