[DOCS] Add Documentation for English Communication (Sem 1)

[Kartikeyji17]

Description

Add structured and beginner-friendly documentation for the English Communication subject under Semester 1.

Suggested Changes

I'd like to contribute documentation covering:

• Basics of Communication (Types, Process, Barriers)
• Written Communication (Emails, Reports, Letters)
• Verbal & Non-Verbal Communication
• Reading Comprehension
• Grammar Essentials
• Presentation & Public Speaking Tips
• Group Discussion & Interview Skills

Content will follow the existing documentation style — beginner-friendly, properly formatted markdown.

Additional Notes

This subject is listed under Sem 1 on the site but has no content yet.
The subject is currently marked as "Coming Soon" on the platform. Adding proper documentation will help first-year CSE students access organized learning material in one place.

Hii @pushkarscripts, I would like to work on this under GSSoC'26. I'm a CSE student who has already completed this course, so I'll be able to do this.

Please assign docs updation issue to me.
