Anthony Lio 7fb2e8cd42 fix(docs): repeated shiki grammar registration (#50501) ...

## What kind of change does this PR introduce?

bug fix alternative to #50492

## What is the current behavior?

[#50239](https://github.com/supabase/supabase/pull/50239) introduced
repeated shiki grammar registration. duplicate injection rules
accumulate between code blocks, slowing later tutorials enough to hit
the 60-second build timeout

## What is the new behavior?
- reuses one highlighter with all languages loaded once
- restores previous highlighting approach + startup cost while keeping
the page-size savings

## Summary by CodeRabbit

## Enhancements

* Code blocks now preload syntax highlighting for all supported bundled
languages, including SQL, Markdown, and TypeScript.
* Highlighting uses a shared configuration and theme for consistent
rendering across code blocks.
* Concurrent code block renders share a single highlighter
initialization.
* Language handling and syntax-highlighted output are more consistent
across supported, unsupported, aliased, and plain-text code blocks.
