Replace Social Links TBD on Footer with social link icons

**Is your feature request related to a problem? Please describe.**
Many students and young adults interested in helping or advocating to implement restorative justice in Milwaukee use social platforms over email and website forums. We need to communicate progress about features and where we need help to yound technologists, developers, and marketers. Therefore, I (@paul-rinaldi ) will likely create a Twitter, Facebook, and Instagram for WDP once this issue is finished; and so, **the only ask on this issue is to add a Facebook, Twitter, and Instagram icon with default links to those websites**

**Describe the solution you'd like**
- Replace "social links tbd" with material ui icons (or ionicons etc.) of Facebook, Twitter, and Instagram icon with default links to those websites
- The icons should have enough spacing between each other but not be too far apart
- The color should be white outline or black outline, not filled icons

**Describe alternatives you've considered**
None

**Additional context**
None

Individua il footer e il testo esistente "social links tbd", quindi verifica come il frontend JavaScript/React esegue il rendering dei link e delle icone del footer. Il lavoro è completato quando le icone di Facebook, Twitter e Instagram vengono visualizzate con link ai siti web predefiniti, una spaziatura adeguata e uno stile con contorno anziché pieno.

Scritto dal modello di indicizzazione a partire dal testo della issue.
