usecase

[usecase] [autogenerate] Render if_exists and if_not_exists parameters in
CreateTableOp, CreateIndexOp, DropTableOp and
DropIndexOp in an autogenerate context. While Alembic does not
set these parameters during an autogenerate run, they can be enabled using
a custom Rewriter in the env.py file, where they will now be
part of the rendered Python code in revision files. Pull request courtesy
of Louis-Amaury Chaib (@lachaib).
[usecase] [environment] Enhance version_locations parsing to handle paths containing newlines.

[usecase] [operations] Added support for Operations.create_table.if_not_exists and
Operations.drop_table.if_exists, adding similar functionality
to render IF [NOT] EXISTS for table operations in a similar way as with
indexes. Pull request courtesy Aaron Griffin.

[change] [general] The pin for setuptools<69.3 in pyproject.toml has been removed.
This pin was to prevent a sudden change to PEP 625 in setuptools from
taking place which changes the file name of SQLAlchemy's source
distribution on pypi to be an all lower case name, and the change was
extended to all SQLAlchemy projects to prevent any further surprises.
However, the presence of this pin is now holding back environments that
otherwise want to use a newer setuptools, so we've decided to move forward
with this change, with the assumption that build environments will have
largely accommodated the setuptools change by now.
