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
