Docs: Fix grammar, typos, and formatting issues across documentation

[hmbashar]

Summary

This PR addresses multiple grammar, typo, and formatting issues found throughout the WordPress Playground documentation to improve readability and consistency.

Changes Made

Critical Fixes

1. Incorrect backtick characters (developers/07-xdebug/02-getting-started.md)
   • Fixed: ´.vscode/launch.json´ → `.vscode/launch.json`
   • This was preventing proper code formatting in the rendered documentation

Grammar Improvements

2. Missing words and articles

   • "Now you connect a debugger" → "Now you can connect a debugger"
   • "Here's a very example" → "Here's a very simple example"

3. Sentence structure

   • "Suppose you're not familiar with the tool. In that case, we recommend" → "If you're not familiar with the tool, we recommend"
   • "prioritizing easy installation" → "prioritizing ease of installation"

4. Incorrect conjunctions

   • "the same than contributing" → "the same as contributing"

5. Verb corrections

   • "Allow testers run branches" → "Allows testers to run branches"
   • "report it using" → "report them using"

Formatting & Consistency

6. Consistent file extension formatting

   • "Download as zip" → "Download as .zip"
   • "Import from zip" → "Import from .zip"

7. Parallel structure in lists

   • Changed "It creates a .zip" → "Creates a .zip file"
   • Changed "It allows you to recreate" → "Allows you to recreate"

8. Punctuation improvements

   • Added missing commas for better readability
   • Fixed spacing around en dashes: "(you're here)–" → "(you're here) –"

9. Capitalization

   • "gutenberg" → "Gutenberg" (proper noun)

10. Workflow terminology

    • "on your developer flow" → "in your developer workflow"
