feat(blog): card implemented to blog page

[mabsattar]

Description

Added a Card component and implemented the component to all markdown files in the blog directory to display the cards.

Additional Notes

I had to use URL's for clickmore button, when users click it'll show the full content in a separate page. Also, i modified double quotes with " in a few to be able to implement the component without any issues.
