feat(snippets): seperate nodejs snippet, add corepack installation

[avivkeller]

Fixes #7555

This PR does three things:

1. It adds a new corepack.bash snippet to install Corepack in Node.js >25
2. It moves the "Verify Node.js" step to it's own snippet to avoid duplication.
3. It moves currentPlatform's destructuring into the useMemo call to avoid un-needed recalculations (+ moves that to a seperate function)

Pull Request Overview

This PR refactors Node.js installation snippets and improves the snippet processing component by extracting common verification steps and adding Corepack installation support for Node.js v25+.

• Adds a new Corepack installation snippet for Node.js versions 25 and above where Corepack is no longer bundled
• Refactors the ReleaseCodeBox component to improve performance and maintainability by separating concerns into focused hooks
