[I] [Tech Debt] Update FAQ: cross-language async limitation is outdated [flink-agents]
wzhero1 opened a new issue, #755:
URL: https://github.com/apache/flink-agents/issues/755
### Search before asking
- [x] I searched in the [issues](https://github.com/apache/flink-agents/issues) and found nothing similar.
### Description
Since commit 05ed9910 (`[runtime] Support async execution for cross language resources`), cross-language resources support async execution on Flink runtimes with pemja ≥ 0.6.2.
However, `docs/content/docs/faq/faq.md` still states:
> **Cross-language async limitation**: When using cross-language resources (e.g., calling Java integrations from Python or vice versa), async execution is not supported. Cross-language calls always execute synchronously regardless of your JDK version.
This is incorrect and misleads users into thinking cross-language async is impossible, potentially causing unnecessary native re-implementations.
The "Native Integration Support Matrix" preamble also says "cross-language calls do not support async execution", which is equally outdated.
Both sections need to be updated to reflect the conditional support (version-gated by Flink runtime).
