Joshen Lim ac0d4563d6 Add GH token for fetchAgentSkills to mitigate rate limits (#50106)
## Context

As per PR title - just a nice to have as our `www` preview builds
occasionally fail, likely due to rate limits on the GH API

Env var `AGENT_SKILLS_GITHUB_TOKEN` has been added to the `www` app on
Vercel

## Summary by CodeRabbit

* **Chores**
* Added optional GitHub authentication support for retrieving agent
skills.
* Preserved existing request behavior when no authentication token is
provided.

/**
* Fetches the latest agent-skills index.json from supabase/agent-skills and
* writes it to public/.well-known/agent-skills/index.json.
*
* Skill URLs in the published index.json are absolute GitHub Release asset
* URLs — no rewriting needed on this side.
*
* Spec: https://github.com/agentskills/agentskills/pull/254
* Uses AGENT_SKILLS_GITHUB_TOKEN if set to avoid GitHub's unauthenticated
* rate limit (60 req/hr per IP, shared across Vercel build machines).
