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.

将 v0.6.4 的发行说明与 issue 中链接的 JDBC v2 Environment 要求页面进行比较，并确认当前支持的最低 JDK 版本。更新相互冲突的文档引用，使其说明相同的要求，然后验证这两个页面以及任何相关的发行文档是否使用一致的措辞。
