[STYLE CHANGE] Improving hero section on home page

**Description:**

For now, there are some styling issues in the Desktop view:
1. First the text sizes on the hero section are too small to read, and
2. secondly white color of text on a green background is not more readable and
3. the position of the "om logo" is not proper as per the UI, if it would be at the top of the "MOKSH" title or in parallel with it then it will look more attractive and fascinating.

Styling issues in mobile view:
1. Text sizing of each paragraph is not proper or the same.
2. The position of the "Om" logo is not proper.
