chore(docs): improve visual appearance of badges in README.md (#8928)

# Description
This Pull Request improves the visual appearance of the badges in the
README.md file by removing unnecessary line breaks between the badge
images, eliminating the unwanted blue link lines that previously
appeared and resulting in a cleaner and more cohesive look.

## What
Removed unnecessary line breaks between badge images in the README.md
file to eliminate the unwanted blue link lines and improve the overall
visual presentation.

## Why
Previously, the badges were displayed with line breaks between them,
causing blue link lines to appear, which disrupted the clean look of the
badges. By removing these line breaks, the badges now appear without the
blue link lines, providing a more cohesive and visually appealing
README.

## How
Removed the line breaks between badge images in the README.md file.
