Revert some typing commits

[mkmkme]

Issue #162 revealed that the issues with typing in valkey-py are quite a bit deeper and require some rework of internal classes. The changes introduced in those commits turned out to not fix anything.

At this point we need to publish the new beta because of accumulated fixes since 6.1.0b1. The typing system fixes will be introduced later.

Closes #162
