[bot] Document Vim mode GA, /goal command, plugin CLI restructure, and Copilot app updates

[github-actions]

What's new

Reviewed GitHub Copilot CLI releases (github/copilot-cli, v1.0.83–v1.0.84-4) and GitHub Copilot app releases (github/app, v1.1.15–v1.1.17) from the past week. github.blog, code.visualstudio.com, and nishanil.github.io were unreachable from this environment's network policy, so this update is sourced from the CLI/app release notes via the GitHub API.

Notable changes found:

• Vim mode graduated to GA (v1.0.84) — /vim and editorMode: vim now available to everyone
• /goal command (v1.0.84) — new alias for /autopilot <objective> to keep autopilot focused on a persistent objective, with a pinned goal panel
• Plugin CLI command restructure (v1.0.84) — copilot instruction list/copilot lsp list replace --kind flags; copilot plugin/mcp/skill enable|disable replace copilot plugins enable/disable --plugin|--mcp|--skill; copilot skill add [--project] replaces copilot plugins install --skill [--scope project]; --json added to more plugin subcommands
• Copilot app: pull request description attachments now support pasting/dragging images and videos (v1.1.15); MCP servers can now be installed via a deep link with a prefilled review form (v1.1.15)

Sections updated

• website/learning-hub/copilot-configuration-basics.md — added editorMode setting + Vim mode note, added /goal command documentation
• website/learning-hub/installing-and-using-plugins.md — documented the v1.0.84 CLI command restructure (instruction/lsp list, plugin/mcp/skill enable-disable, skill add)
• website/learning-hub/github-copilot-app.md — added PR media attachments and MCP deep-link install sections

cli-for-beginners pages were intentionally left untouched per the update policy.
