docs: clarify SLES s390x scope in engine install platform table (#24863)

The platform table on `engine/install/_index.md` listed `SLES` with an ❌
in the s390x column, which reads as if SLES is unsupported in general.
The linked `sles.md` is actually scoped to SLES on s390x (the page's own
`linkTitle` is already `SLES (s390x)`).

Align the table label with the page's `linkTitle` so the
architecture-specific scope is visible without clicking through.

Fixes #24862

-## Docker Engine is no longer available for SLES
-
-> [!IMPORTANT]
->
-> Docker Engine packages are **no longer available** for SUSE Linux Enterprise Server (SLES) on the **s390x** architecture (IBM Z).
-
-IBM has made the decision to discontinue building and providing Docker Engine
-packages for SLES s390x systems. Docker Inc. never directly built these packages
-and was only involved in their deployment.
-
-## What this means
-
-- New Docker Engine installations are not available for SLES s390x
-- Existing installations will continue to work but will not receive updates
-- No new versions or security updates will be provided
-- The Docker package repository for SLES s390x is no longer maintained
-
-## If you have Docker currently installed
-
-If you currently have Docker Engine installed on a SLES s390x system:
-
-- Your existing Docker installation will continue to function
-- No automatic updates will be available
-- You should plan accordingly for your containerization needs
-- Consider the security implications of running software without updates
-
-## Next steps
-
-For questions about this decision or alternative solutions, contact IBM support.
