Share RICH_TEXT_V2 field value override between REST and GraphQL APIs (#10912)

Fixes issue #10606.

This PR makes `RICH_TEXT_V2` field behavior in REST API matche the
current behavior in GraphQL API:

Currently both `markdown` and `blocknote` fields must be included in the
request, one of them can be `null`. The field with a `null` value will
be filled by the converted value of the other field.

In other words, this works:
```
curl http://localhost:3000/rest/notes \
  --request POST \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIyMDIwMjAyMC0xYzI1LTRkMDItYmYyNS02YWVjY2Y3ZWE0MTkiLCJ0eXBlIjoiQVBJX0tFWSIsIndvcmtzcGFjZUlkIjoiMjAyMDIwMjAtMWMyNS00ZDAyLWJmMjUtNmFlY2NmN2VhNDE5IiwiaWF0IjoxNzQxODA1MzQyLCJleHAiOjQ4OTU0MDUzNDEsImp0aSI6ImZlMzU0NTBkLTlhMDMtNGE2ZS04ODVjLTBlNTU3M2Y3YTE0NiJ9.6_g8cwoSE7ZCX1Zzsw44gZIyBdLKNsnDqMOmm1bKik0' \
  --data '{
  "position": 1,
  "title": "a",
  "bodyV2": {    
    "markdown": "test4\n\ntest3\n\n# test1\n",
    "blocknote": null
  },
  "createdBy": {
    "source": "EMAIL"
  }
}'
```

And this does not work:
```
curl http://localhost:3000/rest/notes \
  --request POST \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIyMDIwMjAyMC0xYzI1LTRkMDItYmYyNS02YWVjY2Y3ZWE0MTkiLCJ0eXBlIjoiQVBJX0tFWSIsIndvcmtzcGFjZUlkIjoiMjAyMDIwMjAtMWMyNS00ZDAyLWJmMjUtNmFlY2NmN2VhNDE5IiwiaWF0IjoxNzQxODA1MzQyLCJleHAiOjQ4OTU0MDUzNDEsImp0aSI6ImZlMzU0NTBkLTlhMDMtNGE2ZS04ODVjLTBlNTU3M2Y3YTE0NiJ9.6_g8cwoSE7ZCX1Zzsw44gZIyBdLKNsnDqMOmm1bKik0' \
  --data '{
  "position": 1,
  "title": "",
  "body": "",
  "bodyV2": {    
    "markdown": "test4\n\ntest3\n\n# test1\n"
  },
  "createdBy": {
    "source": "EMAIL"
  }
}'
```

It would be nice not to require the null value, maybe let's make that a
separate PR?
