feat(cli): cherry-pick PR #15402 — use alias name for template id

[Copilot]

Cherry-pick of PR #15402 to dev. Adds user-friendly alias names for template IDs in the CLI, so users can use short, readable names (e.g., declarative-agent, bot, tab) instead of internal template names like copilot-gpt-basic.

Template metadata

• Added optional alias field to Template interface (templates/src/metadata/interface.ts, packages/fx-core/.../interface.ts)
• Added TemplateAlias enum to templates/src/templateNames.ts
• Populated alias on templates across declarativeAgent.ts, graphConnector.ts, teams.ts, allTemplates.json, defaultGeneratorTemplates.json
• Renamed foundry-agent → foundry-agent-to-m365 (id and name)

CLI logic (create.ts, listTemplates.ts)

• Capability choices now include both alias and name for backward compatibility: [alias, name]
• Non-interactive mode resolves alias → canonical name before passing to core:

  atk new -c declarative-agent -n myapp -i false   # previously required: copilot-gpt-basic
  

• Language preset logic now also triggers when alias is matched (not just name)
• listTemplates table displays alias as the Capability(Id) column when available
• Extracted groupTemplatesByName as a named export for testability

Other

• advancedDASettingUrl updated to https://aka.ms/atk-da-share
• launch.json updated to use declarative-agent in default debug args
