[Docs] Update node supported version

[fellyph]

This pull request updates the documentation for the Playground CLI and contributing guides across multiple languages to require Node.js version 22.12 or newer (previously 20.18 or newer). This ensures consistency and clarity about the minimum Node.js version needed for development and contribution.

Documentation updates for Node.js version requirements:

• Updated the required Node.js version for the Playground CLI from 20.18 to 22.12 in the main English documentation (04-wp-playground-cli.md) and its translations in Spanish, Japanese, and Brazilian Portuguese.
• Updated the Node.js version requirement in contributor guides for English, Bengali, Spanish, Gujarati, Italian, Japanese, and Brazilian Portuguese, ensuring all mention Node.js 22.12 or newer.

Minor formatting corrections:

• Fixed code block formatting in the Spanish contributor guide for proper display of bash commands.

@fellyph it looks like our declared minimum Node.js version is still v20.x here:

wordpress-playground/package.json

Lines 226 to 229 in 4898cb8

	"engines": {
	"node": ">=20.18.3",
	"npm": ">=10.1.0"
	},

Is this something we need to change?

[fellyph]

@brandonpayton, we had a change on nvmrc https://github.com/WordPress/wordpress-playground/pull/3114/changes to 22.12. Should we change the package.json as well? I would send this change in a separate PR

@fellyph yep, we need to update it in package.json, package-lock.json, and maybe more places. It would be a good idea to search for other references to 20.18.3 in the project as well.

@brandonpayton I have created a PR to update the package.json: #3247
