Title

Update Link Container

Description

Added event listeners to inputs in the link class, added a prototype isValidURL function that uses a regex to check if a string is a valid URL. Added function setIcon that fetches the corresponding icon or the default icon.

Added default.png for the icon class if there is no link in socialLinks or if ${key.png} exists.

Implemented previewLink(button), matching inputValue with a key in socialLinks if possible and handling the username.
