Add featured certificates

[CreedsCode]

This Issue is corresponding to the card of the project milestone.

https://github.com/StanlyLife/Certify/projects/1#card-36822780

Requirements:

• Max 3

My first thoughts on implementation: UX

• In the edit add a star icon to add it to the featured certifications
• Show on profile between ProfileDetails and TableWrapper those favs in a 3row layout. That transforms with the amount of favs. ex. 1 in the middle on two one left right at three there is one centered in the middle the rest goes to left & right side.

Backend

• Store a list with the featured certifications.

It's possible to use the edit certifications and have a star icon.

• requires less code
• cleaner ui

I already thought about the start icons and I liked it, idk why I didn't mentioned that, because the idea is so great! I add it to the listing.
