chore: remove pull_request trigger and revert whitespace change

pull_request trigger was added for pipeline testing only — pipeline is
now validated end-to-end. Removing it prevents publish-docs from running
on every branch push and creating unwanted PRs against agent-observability-docs.

Reverts whitespace-only change in auto-generate-api-client.sh.
