[azure.ai.agents] Register update for 1.0.0-beta.3 and beta.4

[huimiu]

Fixes: #8974

Combines the two automated single-version registry updates into one PR so azure.ai.agents 1.0.0-beta.3 and 1.0.0-beta.4 land together for the Beta AI Agents release.

Changes

• cli/azd/extensions/registry.json: add the 1.0.0-beta.3 and 1.0.0-beta.4 version entries for azure.ai.agents (appended after 1.0.0-beta.2).
• cli/azd/cmd/testdata/TestFigSpec.ts: update the azd ai agent sample list --type description snapshot to agent, azd, azure.yaml. TestFigSpec installs the latest extension from the local registry, so once beta.4 resolves it pulls in the new azure.yaml template type.

Supersedes

• [azure.ai.agents] Registry update for 1.0.0-beta.3 #8965 — [azure.ai.agents] Registry update for 1.0.0-beta.3
• [azure.ai.agents] Registry update for 1.0.0-beta.4 #8972 — [azure.ai.agents] Registry update for 1.0.0-beta.4

The combined diff equals both bot PRs together: registry.json +176 (88 + 88) and the same single-line snapshot update.

Pull request overview

Registers azure.ai.agents extension releases 1.0.0-beta.3 and 1.0.0-beta.4 in the local extension registry so azd can install those versions, and updates the Fig completion snapshot to reflect the new azure.yaml sample template type surfaced by the extension.

Changes:

• Add azure.ai.agents 1.0.0-beta.3 and 1.0.0-beta.4 entries (artifacts/checksums, required azd version, capabilities, providers, dependencies) to cli/azd/extensions/registry.json.
• Update the azd ai agent sample list --type description snapshot to include azure.yaml in supported values.

Verified both release tags exist with all platform artifacts, registry entry structure matches the established beta.2 pattern, and the FigSpec snapshot update is correct.
