Add support for `actors/socials`

[LucJosin]

Description

Add support to POST, UPDATE and DELETE actors/socials

Currently we can only add actor socials using POST and socials field when creating a new actor

E.g:

{
  "first_name": "...",
  "last_name": "...",
  "socials": [
    {
      "social": "Lorem",
      "handle": "@john",
      "url": "https://lorem.com/@john"
    }
  ]
}
