docs: document snippet variables in code blocks

[mintlify]

Summary

Snippet variables (props) can now be referenced inside fenced code blocks within a snippet, and the value passed in as a prop replaces the placeholder when the page renders.

Changes

• Added a new section to create/reusable-snippets.mdx covering snippet variables in code blocks, including a usage example.
• Mirrored the update across the French, Spanish, and Chinese translations.

Context

Documents the change introduced in mintlify/mint#7854, which added support for snippet variable replacement inside code block content.

---

Note

Low Risk
Low risk documentation-only change; updates add guidance/examples and translated copies without affecting runtime behavior.

Overview
Documents that snippet props can be interpolated inside fenced code blocks using {variableName}, with an example snippet (installCommand) and import usage.

Mirrors the same new section across the Spanish, French, and Chinese versions of create/reusable-snippets.mdx.
