Social media icon links

need to add social media icons at bottom of popup.

should probably create an icon for website as well probably this - 🌐

current social networks added to the sheet are
- facebook
- twitter
- linkedin
- mastodon
- github (not social but relevant)
- youtube
- instagram

TODO:

- [ ] Gather all relevant icons from branding sites
- [ ] Add function that creates an icon row for the popup
- [ ] Add form inputs for every option
- [ ] Form inputs should probably only appear if user wants to add
- [ ] Look into making other inputs in form expandable as well

This project is open source, so if anyone wants to help, this is a relatively easy thing to jump in on
