docs(dbapi): fix pyodbc connect method example

[popsiclelmlm]

Description

Fixes #707.

Summary

Updates the DBAPI documentation example for pyodbc to wrap the module-level connect function instead of Connection.

Reproduction

The issue report shows trace_integration(pyodbc, "Connection", "odbc") does not produce DB spans for pyodbc, while changing the connect method name to "connect" makes instrumentation work.

Root cause

The documented pyodbc example uses the wrong connect method name. trace_integration and wrap_connect both expect the DBAPI module function used to create connections.

Changes

• Changes the pyodbc trace_integration example from "Connection" to "connect".
• Changes the pyodbc wrap_connect example from "Connection" to "connect".

• git diff --check
