RS: updates for INCREX and array commands

[dwdougherty]

@kaitlynmichael, this PR is the one that we discussed a while ago. It targets the RS version that will include Redis 8.8.

Note

Low Risk
Documentation-only compatibility and behavioral notes; no runtime or API code changes.

Overview
Updates Redis Software 8.8 compatibility documentation for the preview array command family and INCREX.

For all AR* commands, Redis Software standard databases are now marked supported (Active-Active and Redis Cloud stay unsupported). The central data type commands compatibility table and each command page’s compatibility section are aligned.

INCREX is documented as supported on Redis Software standard and Active-Active (with a caveat), still unsupported on Redis Cloud. A new Active-Active databases section explains that LBOUND/UBOUND are enforced per replica locally, so concurrent increments can merge above/below bounds after sync.

The arrays data-type guide adds an explicit note that arrays are not supported in Active-Active databases.
