    Limit SQLAlchemy to < 1.4.0 for 2.2.* line (#21235)
    
    The recent release of FAB 3.4.4 has unblocked us from upgrading
    SQLAlchemy to 1.4.* version. We wanted to do it for quite some
    time however upgrading to 1.4.* of sqlalchemy and allowing our
    users to use it for 2.2.4 is a bit risky.
    
    We are fixing resulting "aftermath" in the main branch and as
    of this commit there are two fixes merged and remaining MsSQL
    problem. The MSSql problem does not affect 2.2.4 as MsSQL will
    be available only starting from 2.3.0, however the two other
    problems have shown that SQLAlchemy has a potential to break
    things and we might want to test it more thoroughly before
    releasing 2.3.0.
    
    The problems in question are #21205 and #21228. Both were only
    test problems but the indicate that there might be more hidden
    issues involved.
    
    In order to limit risks, this PR proposes to limit SQLAlchemy
    for 2.2.* to < 1.4.0. This will allow to upgrade FAB and
    related dependencies without opening up Airflow to upgrade to
    SQLAlchemy 1.4 (yet).
