Resolving issue #10774

[apilaskowski]

This change assumes that previous PR #10771 is already merged.
I tested it both on databases with Airflow versions 2.5.3 and 2.6.3.

@iennae is there something that I should do to unblock this? So it can be released?

[leahecole]

Same as before, ask @rafalbiegacz for review #2!

It fails for me on 2.5.3

[2024-01-09, 20:57:37 UTC] {airflow_database_cleanup.py:471} INFO - Deleting sessions...
[2024-01-09, 20:57:37 UTC] {airflow_database_cleanup.py:489} ERROR - (sqlite3.OperationalError) unrecognized token: ":"
[SQL: SELECT * FROM session WHERE expiry < now()::timestamp(0);]
(Background on this error at: https://sqlalche.me/e/14/e3q8)

I'm running it via https://cloud.google.com/composer/docs/composer-2/run-local-airflow-environments

Edit: I also ran it on a "real" environment in Cloud Composer and it fails there as well.
