chore: add chrfwow to Java approvers

@chrfwow has been contributing significantly to our Java implementations:

- finally hook change in SDK: open-feature/java-sdk#1246
- flag metadata support in the flagd java provider: open-feature/java-sdk-contrib#1122

And most recently identified a deadlock in the Java SDK, opened an issue describing it, and has been helping to guide the fix by a new contributor: open-feature/java-sdk#1314

I'm nominating them for Java approver. @chrfwow please approve or 👍 this PR for signal your interest.
