Bug: Missing chapters show on website homepage

[VanshGarg06]

Describe the bug

There are some chapters missing on the listing on the homepage which should be added so that the viewer and users know what is inside the book. There are several topics which are missing like IN operater after where clause, after Join SQL | DDL, DML, DQL, DCL and TCL commands, SQL subqueries, SQL Union clause, Relational keys, Logical operator keywords, Having clause, Essential MySQL functions, Triggers in SQL, Transaction Control Language, Data Control Language and adter dump command we have Automated backup.

To Reproduce

1. Go to Website
2. Download the book
3. Compare Index and listing on the website
4. See Error

Expected behavior

The listing on the homepage is missing some of the elements of the book that are present in the book as i have downloaded the book and most of the topics of the books are not mentioned in the listing of the Homepage. The listing should match with the index of the book so that users could know what book will be including.

Screenshots

Additional context

Please assign this issue to me as i wanted to make the listing as same as the book downloaded from the website as if users could know that what all are included it will create the impact on users to download the book. Please assign this issue to me under @Hacktoberfest , @hacktoberfest-accepted and @Hacktoberfest2025
