Bump pydocket>=0.19.0, drop fakeredis pin (#3822)

pydocket 0.19.0 fixes the fakeredis 2.35.0 FakeConnection rename
internally, so we no longer need to carry the fakeredis ceiling
ourselves. Removes the direct fakeredis[lua]<2.35.0 dependency from the
tasks extra entirely — it's just a transitive of pydocket now.
