**Describe the unexpected behaviour**

An error is received when inserting to a table with JSON column type:

```
Received exception from server (version 22.3.3):
Code: 36. DB::Exception: Received from localhost:9000. DB::Exception: Explicitly specified names of tuple elements cannot start with digit. (BAD_ARGUMENTS)
```

**How to reproduce**
```sql 
set allow_experimental_object_type=true;
CREATE TABLE json_test (data JSON) ENGINE=MergeTree PRIMARY KEY tuple();
INSERT INTO json_test (data) VALUES('{ "12344": true }');
```
result: 
```
INSERT INTO json_test (data) FORMAT Values

1 rows in set. Elapsed: 0.002 sec. 

Received exception from server (version 22.3.3):
Code: 36. DB::Exception: Received from localhost:9000. DB::Exception: Explicitly specified names of tuple elements cannot start with digit. (BAD_ARGUMENTS)
```

* Which ClickHouse server version to use
22.3.3.44


**Expected behavior**
It must be possible to insert such JSON to the table since its a valid JSON:

```
select isValidJSON('{ "12344": true }');

┌─isValidJSON('{ "12344": true }')─┐
│                                1 │
└──────────────────────────────────┘
```
