Raúl Barroso 01958e520f tests: add regression test for skills list (#47819) ...

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Adds regression tests for something we noticed today. AI skills weren't
being loaded on https://supabase.com/docs/guides/ai-tools/ai-skills, so
while we fixed it, we wanted to make sure we could identify this faster.

## What is the current behavior?

Less tests. AI skills loading and not 

## What is the new behavior?

Two tests, no new workflows — both ride existing CI:

- **Unit test** (`AiSkills.utils.test.ts`) mocks GitHub, checks the
parsing/shaping logic (dir filtering, frontmatter, install command,
sorting, empty→fallback). Runs on every PR.
- **Smoke test** (`AiSkillsIndex.smoke.test.ts`) hits the live page and
asserts the skills table actually rendered. Runs in the daily docs smoke
job, and can be pointed at any environment via `DOCS_SMOKE_URL`.

Small supporting change: `getAiSkillsImpl` is now exported so the unit
test can call it directly.
