docs(docs/ai-coder/agents): note OpenAI as a supported computer-use provider (#24967)

PR #24772 (merged 2026-05-04) added OpenAI alongside Anthropic for
computer use, plus an admin selector under the virtual desktop toggle.
Three places in the agents docs still said "Anthropic only" — this
updates them.

No other content changes. Anthropic is still the default.

@nickvigilante — heads up, the kind of release-train drift we keep
hitting:

- Feature is on `main`, so docs on `main` need to describe it.
- Feature is **not** in `release/2.33` and **not** in `v2.34.0-rc.0`
(both cut before #24772 merged). It will ship in v2.34.
- `coder.com/docs` follows `main`, so once this lands, v2.33 users see
"OpenAI is supported" and find no toggle.

Fwiw our [`doc-check`
workflow](https://github.com/coder/coder/blob/main/.github/workflows/doc-check.yaml)
would have caught this on #24772 — it's exactly what it's for. It [did
trigger](https://github.com/coder/coder/actions/runs/25326759671) but
the chat-create step errored out (curl exit 22) and nobody re-ran it, so
the analysis never happened. Worth tightening that path so a transient
API blip doesn't silently skip the check.
