feat(streams): support entries_read and lag for XINFO GROUPS (#1952)

entries_read and lag have been added to the output of XINFO GROUPS since Redis 7.0. This patch supports both for Dragonfly. This patch also fixes a bug that incorrectly sets the initial value of entries_read when a consumer group is created.
