Use sqlalchemy version in sqlalchemy commenter instead of opentelemetry library version (#2404)

* Use sqlalchemy version in sqlalchemy commenter instead of opentelemetry library version

The SqlAlchemy commenter is currently using the library version in the comment it emits, e.g.:

```
{
  'db_driver': 'psycopg2', 
  'db_framework': 'sqlalchemy:0.45b0'
}
```

We should instead be using the sqlalchemy version here, as SqlCommenter did before

* Fix lint

* Fix lint

* Add CHANGELOG entry
