fix(packages/components/src): MDX indentation

[code-qtzl]

Issue: #226

Summary

When CodeBlock is used inside MDX/JSX with template literals, the code content inherits the surrounding JSX indentation, causing it to render with extra leading whitespace. This fix adds a dedentCode utility that detects the minimum indentation across all non-empty lines (after the first) and strips it uniformly, so the rendered code aligns correctly regardless of nesting depth.

Two Storybook stories (MDXIndents, MDXIndentsDeeplyNested) are added to cover typical and deeply-nested JSX indentation scenarios.

Note

Medium Risk
Touches core code rendering/extraction used by CodeBlock/CodeGroup (whitespace normalization affects both display and copied text), which could subtly change formatting in existing docs. Other changes are minor (removing an unintended clipboard side effect and adding a TOML preset).

Overview
Fixes MDX/JSX template-literal indentation issues by routing CodeBlock/CodeGroup text extraction through getCodeString and adding a dedentCode step in utils/shiki/lib.ts, so leading whitespace from surrounding JSX nesting is stripped consistently (including for copy-to-clipboard).

Removes the side effect that copied the updated URL to the clipboard when an Accordion opens, and adds a toml snippet preset (with optional httpSnippet) to restore a missing language/icon. Also bumps @mintlify/components to 1.0.17 and updates the changelog, plus adds two Storybook stories covering MDX indentation scenarios.
