docs(skills): note the skills CLI command is only in the release candidate

The skills installer ships in the release candidate but is not yet on the
stable release. Add a warning on each page that shows the command, telling
users to run it with the @rc tag until it lands in @latest.

 `npx trigger.dev@latest install-rules` still works as an alias, and `trigger dev` offers to install the skills on first run.
 
 The old task and realtime guidance now lives in the `trigger-authoring-tasks` and `trigger-realtime-and-frontend` skills, alongside two new skills for building `chat.agent` AI agents. See [Skills](/skills) for the full list and supported assistants.

 The CLI detects your installed AI tools, lets you pick which skills to install, and writes each one into that tool's native skills directory (`.claude/skills/`, `.cursor/skills/`, `.github/skills/`, `.agents/skills/`). It also adds a one-line pointer to your primary instructions file (`CLAUDE.md`, `.cursor/rules`, etc.) so your assistant always knows the skills are there and loads the right one on demand.
 
 When you run `trigger dev` for the first time, the CLI offers to install the skills for you.
