Update deprecated OpenJDK links in DEVELOPMENT.adoc (#1468)

Fixes broken links and grammar in DEVELOPMENT.adoc:

- Mailing list URL: openjdk.java.net → openjdk.org (old domain returns
301)
- Truffle FAQ link: old OpenJDK wiki is gone (404) — replaced with
current GraalVM Truffle docs
- Grammar: "enables to run" → "enables you to run"
- Grammar: "jenv use specific" → "jenv uses specific"
