Enhancement: Adding target mode support to sociallinks

[tahacodes]

Hey there,

Thank you for this awesome theme. I really appreciate the beauty and simplicity of it. ❤️

I made a minor change to the "layouts/partials/about.html" file, I added an option to specify the “target” attribute in the Hugo configuration file for social links. By default, the behavior remains as "_self" This means that if users don’t explicitly set a target, it will function just as before.

Thank you for considering this PR!
