Related to issue #36102

This is one of a series of 15 PRs (75 or less per PR) which replace all applicable single backtick code blocks with the triple backtick code blocks plus language postfix (where applicable) to correct the mistakes made by the scripts which made the original translations of the Arabic Guide articles.

NOTES:

• The scope of review for this PR should not focus on indentation or other style issues with the code sections. However, it could be that the original Guide article had the wrong language post-fix (i.e. html should have been css). In those instances, it would be fine to request changes.

• I only included a maximum of 75 files in each PR to make it easier to review on GitHub.
