Add applies_to tags to workflows/Agent Builder schema parameter docs

[Copilot]

PR #5630 renamed outputSchema → schema and added schema to the ai.agent step without applies_to tags. These are 9.4/serverless changes — 9.3 users still need outputSchema docs.

• Parameters table: Restored outputSchema row (tagged stack: preview 9.3); tagged schema row as stack: preview 9.4+, serverless: preview
• Output structure: applies-switch to show correct comment per version
• Structured output example: applies-switch with outputSchema: YAML for 9.3 and schema: YAML for 9.4+/serverless

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.elastic.co
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
