py-sqlalchemy: update to 1.4.48

Version 1.4 is taking on a different focus than other SQLAlchemy releases
in that it is in many ways attempting to serve as a potential migration
point for a more dramatic series of API changes currently planned for release
2.0 of SQLAlchemy. The focus of SQLAlchemy 2.0 is a modernized and slimmed
down API that removes lots of usage patterns that have long been discouraged,
as well as mainstreams the best ideas in SQLAlchemy as first class API features,
with the goal being that there is much less ambiguity in how the API is to be
used, as well as that a series of implicit behaviors and rarely-used API flags
that complicate the internals and hinder performance will be removed.
