URL: https://github.com/apache/airflow/issues/37071
### Apache Airflow version
2.8.1
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
Airflow failed to upgrade from version 2.7.1 to 2.8.1, due to a incompatible
alembic version:

NotImplementedError: SQLAlchemy 2.0+ required
```
### What you think should happen instead?
Alembic version should be pinned to at least version 1.13.0. It then
requires SQLAlchemy to be higher than 1.4, opposed to 2.0 in versions 1.11 and
1.12 ([cfr
https://github.com/sqlalchemy/alembic/blob/rel_1_13_0/alembic/operations/toimpl.py](https://github.com/sqlalchemy/alembic/blob/8bb93a0352e01258131ad8c9945ee500c3bc55cb/alembic/operations/toimpl.py#L109)
### How to reproduce
Run airflow-migrations on version 1.11 or 1.12 when migrating from Airflow
2.7.1 to Airflow 2.8.1
### Operating System
Debian GNU/Linux 11 (bullseye)
