Handle lists in the response of INFO (#3277)

Parse lists in the response of INFO, and even lines where list items are
mixed with key=value items, in which case the overall structure will be
a dict, and the items without value get `True` as their value.

Do maintenance stuff around the latest Redis Stack release. The
Graph module is no longer part of Redis Stack. Skip the tests, to
not break the CI. Backport a couple of fixes done on the master
branch.

Avoid workflows canceling each other out.
