Fixed regression introduced in 2.0.20 via 🎫`9600` fix which attempted to add more formal typing to :paramref:`_schema.MetaData.naming_convention`. This change prevented basic naming convention dictionaries from passing typing and has been adjusted so that a plain dictionary of strings for keys as well as dictionaries that use constraint types as keys or a mix of both, are again accepted. As part of this change, lesser used forms of the naming convention dictionary are also typed, including that it currently allows for ``Constraint`` type objects as keys as well. Fixes: #9284 Fixes: #10264 Change-Id: Ic6561dd65058e4de3a7a393295b9863fc065db13
