doc(arabic): Complete Translation of Arabic Documentation to Arabic

[Iyadchafroud]

Summary

This PR translates the Arabic documentation pages in posts/ar/ from English to proper Arabic. The translations ensure consistency, accuracy, and readability for Arabic-speaking users, covering key topics like installation, API usage, configuration, error handling, and more.

Changes Made

• Translated frontmatter (titles, descriptions, navigation links) to Arabic.
• Translated all headings, descriptions, code comments, and notes to Arabic.
• Preserved code blocks, links, and technical references in their original form for functionality.
• Files updated:
  • posts/ar/intro.md (Getting Started → البدء)
  • posts/ar/example.md (Minimal Example → مثال بسيط)
  • posts/ar/post_example.md (POST Requests → طلبات POST)
  • posts/ar/api_intro.md (Axios API → أكسيوس إي بي أي)
  • posts/ar/instance.md (The Axios Instance → نموذج Axios)
  • posts/ar/cancellation.md (Cancellation → الإلغاء)
  • posts/ar/config_defaults.md (Config Defaults → الإعدادات الافتراضية)
  • posts/ar/handling_errors.md (Handling Errors → معالجة الأخطاء)
  • posts/ar/interceptors.md (Interceptors → المتدخلات)
  • posts/ar/notes.md (Notes → ملاحظات)
  • posts/ar/req_config.md (Request Config → تكوين الطلب)
  • posts/ar/res_schema.md (Response Schema → مخطط الاستجابة)
  • posts/ar/urlencoded.md (URL-Encoding Bodies → أجسام URL-Encoded)

Motivation

The Arabic docs were previously in English, which limited accessibility for Arabic-speaking developers. This translation improves the user experience and aligns with Axios's goal of supporting multiple languages.

Testing

• Verified translations for grammatical accuracy and technical correctness.
• Ensured no breaking changes to code or links.
• Checked rendering in Markdown

Additional Notes

• Translations were done manually to maintain context and idiomatic Arabic.
• No new dependencies or breaking changes introduced.
