Description

Hello,
As per the thread on the user group, we're currently looking at upgrading to solr 9.5.0, from v8.

We have built a fresh solr 9.5.0 from scratch, and have observed that when requesting application/json, binary fields are not quoted - thus resulting in invalid JSON.

I found https://issues.apache.org/jira/browse/SOLR-10653, which looks very similar, and was "fixed" in 9.5.0.

Here's an example (partial) response that you can see (truncated the actual value though):

```
"PARTNER_SITES_ADVERT_STATUS":"EXPIRED",
"DATE_OF_REGISTRATION_EPOCH":1584403200,
"STOCK_ITEM_BINARY_FIELD":OikKAfqLb3JpZ2luU291cmNlQ0....=,
"FUEL_CAPACITY_VALUE":59.0
```
