Fix red develop 391d944fb23e

The merge lane found `develop` red at `391d944fb23e9f3394b7c6ee21da73fe18ab67bc` on its own: no queued PR merges until it is fixed. Failing (tests and gate stages): - `agent-sdk-suite-build-python-ts-conformance` The whole gate log: artifact `8711` on lane task 9202. Make `develop` pass its full gate again. Open a PR as usual: the merge lane merges a PR that fixes some of these and adds no failure even while `develop` is red.

Fixed red develop: regenerated the stale agent-sdk spec page (credential.get row, broken by Task 9182) and reworded its "e.g." so the row isn't truncated. SDK suite + quick gate green; PR #6703 queued to the merge lane. Memory: none applied.
