Inconsistency between documentation and ChangeLogs regarding minimum JDK runtime requirements

### Describe your feedback

- Inconsistency between documentation and ChangeLogs regarding minimum JDK runtime requirements.
- For https://github.com/ClickHouse/clickhouse-java/releases/tag/v0.6.4 , it is mentioned that,

```
Lowest supported Java version will be 11.
Java 11 support will be ended before the end of 2023.
It is recommended to use Java 21.
```

- 

- But https://clickhouse.com/docs/en/integrations/java/jdbc-v2#environment-requirements mentions,
```
Environment requirements
[OpenJDK](https://openjdk.java.net/) version >= 8
```
- 

- This is a bit of a conflict from my perspective. Is the minimum JDK runtime requirement now JDK8, or JDK11?

### Code example

- Probably not.

Compare the v0.6.4 release notes with the JDBC v2 Environment requirements page linked in the issue, and confirm the current minimum supported JDK. Update the conflicting documentation references so they state the same requirement, then verify both pages and any related release documentation use consistent wording.
