Feat: Add PUT/PATCH video endpoint

### Is your feature request related to a problem? Please describe.
We need to add an endpoint for updating the video.

### Describe the solution you'd like
Update video (PUT or PATCH method). Request payload:
```json
{
"title": "string",
"url": "string",
"date_published": "2021-01-14",
"source": "string",
"channel": "string",
"duration": 0,
"archived": false,
"free_to_reuse": true,
"authorized_to_reuse": true,
"category_sections": [
