feat: Add assigneeName to issue assigned activities (#85554)

Originally written by: @gabriellanata; It supersedes: #85399

> When an issue is assigned to a team, the activity only shows the team
ID which is not very visual. I'm adding assigneeName (which matches the
`assignedTo` when requesting an issue's details) to activity data.

If you visit [this
URL](https://us.sentry.io/api/0/organizations/sentry/issues/4704765109/activities/)
you can see the current format of the activity (trimmed data):
```
{
  "activity": [
    {
      "type": "assigned",
      "data": {
        "assignee": "2006237",
        "assigneeEmail": null,
        "assigneeType": "team"
      }
    }
  ]
}
```
The `issues` team is not mentioned in the API, however, the UI handles
it well:

/>

Ideally, we would store less information in `data` and make the
serializer smarter by fetching the models it is indirectly referring to
(see
[code](https://github.com/getsentry/sentry/blob/e96e32a095e1e2ff89c8fb0ea2681848decaf4c3/src/sentry/models/activity.py#L57-L66)).
