In `@docs/source/models/supported-models.md`:
- Line 72: The consolidated table row for NemotronHForCausalLM currently
overstates support; update the `NemotronHForCausalLM` row in
docs/source/models/supported-models.md so that the "Attention Data Parallelism",
"Disaggregated Serving", and "KV Cache Reuse" columns are set to conservative
values (e.g., `Untested`) to match the `NemotronHForCausalLM (Super)` row, or
alternatively add a footnote clarifying that those features are only confirmed
for `NemotronHForCausalLM (Ultra)`; locate the consolidated
`NemotronHForCausalLM` table row and change the three column entries or append a
clarifying footnote referencing the `(Super)` vs `(Ultra)` rows.
