Azure Synapse Serverless: cannot read view definition
#### System information: 
- Windows 10
- DBeaver 22.0.3

#### Connection specification:
- Database type: Azure Synapse "serverless"
- Driver name: Azure SQL Server
- No tunnels or proxies

#### Describe the problem you're observing:
Trying to get the DDL of a view produces a NullPointerException and the definition pane shows:
```
/* ERROR WHILE READING SOURCE:

null
*/
```

In version 22.0.0, view definitions could be obtained, see #15490.

#### Steps to reproduce, if exist:
- Open a view object in this type of database
- Go to Properties -> Definition

#### Include any warning/errors/backtraces from the logs

Session data:

eclipse.buildId=unknown
java.version=11.0.12
java.vendor=Eclipse Foundation
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en
Command-line arguments:  -os win32 -ws win32 -arch x86_64

Connection test shows:

Server:
    Microsoft SQL Server 12.00.214
    Microsoft SQL Azure (RTM) - 12.0.2000.8 
    Mar 31 2022 08:13:33 
Driver:
    Microsoft JDBC Driver 9.2 for SQL Server 9.2.0.0

Output of `SELECT SERVERPROPERTY('EngineEdition')`: 11

`SELECT definition FROM sys.sql_modules WHERE object_id = (OBJECT_ID(N'your_shema_name.your_view_name'))` (adapted to existing schemas and views, obviously) gives no results.
